For a statistics class project, a college student randomly samples 75 men who exercise at a gym regularly and 68 women who exercise at a gym regularly. The college tudent believes that on average men spend more time at the gym each week. The college student records the number of minutes each person exercises in a given week. The college student conducts a hypothesis test at the 5% significance level.
Use the summary statistics to conduct a hypothesis test in StatCrunch. (Open an empty StatCrunch spreadsheet. Choose Stat, T Stats, two sample, with Summary. Adjust the alternative hypothesis as necessary Two Sample T-Test
Sample n Mean Std. Dev.
Men 75 65.7 13.9
Women 68 64.8 9.6
What conclusion can you draw from the output?
i. The data provide sufficient evidence to reject the null hypothesis and to conclude that the mean amount of exercise (minutes) is greater for men than for women at this gym.
ii. The data provide sufficient evidence to conclude that there is no difference in the mean number of minutes exercised per week for men and women.
iii. The data do not provide sufficient evidence to conclude that the mean number of minutes exercised per week is larger for men than for women at this gym
Answer:
iii. The data do not provide sufficient evidence to conclude that the mean number of minutes exercised per week is larger for men than for women at this gym
Step-by-step explanation:
1) The hypotheses are
H0: u1 ≤ u2 against the claim Ha: u1 > u2
The men spend less or equal time than the women at the gym each week
vs
the men spend greater time than the women at the gym each week
2) The test statistic is
t= (x1`- x2`) / √ s1²/n1+ s2²/n2
t= 65.7- 64.8/√(13.9)²/75 + (9.6)²/68
t= 0.9/√2.57613 +1.35529
t=0.4539
and the degrees of freedom is
3) υ = [s₁²/n1 + s₂²/n2]²/ (s₁²/n1 )²/ n1-1 + (s₂²/n2)²/n2-1
=[(13.9)²/75 + (9.6)²/68]²/ [(13.9)²/75 ]² /74 + [ (9.6)²/68]²/67
= 139
The degrees of freedom is always rounded in this calculation
4) The Critical region is [1.656, ∞]
5) t-score is outside of the critical region, so there is not enough evidence to reject H₀.
iii. The data do not provide sufficient evidence to conclude that the mean number of minutes exercised per week is larger for men than for women at this gym

A cylinder has a radius of 8 cm and a height of 4 cm what is the approximate value of the surface area of the cylinder
Area of cylinder = curved area + 2 x base circle
Circles = 2 x π(8)² = 128π cm²
Curved area = circumference of circle x height of cylinder
Circumference of circle = 2πr = 2π(8) = 16π cm
Curved area = 16π x 4 = 64π cm²
Total surface area = 128π + 64π = 192π cm² = 603.19cm² (5sf)
Find the median and mean of the data set below:
5, 7, 3, 36, 7, 23
Ed
Answer: mean is 13.5 and median is 7
Step-by-step explanation:
to get median you do (7+7)/2 and get 7 and for the mean you just add all of the numbers and divide by how many numbers there are. Basically it is 81/6 to get 13.5
Answer:
Median = 7
Mean = 13.5
Step-by-step explanation:
To find the median, put them in increasing order:
3, 5, 7, 7, 23, 36
cross out the values on the ends until you meet in the middle:
/, 5, 7, 7, 23, /
/, /, 7, 7, /, /
Find the average of the two middle numbers: (7+7)/2 = 7
Median = 7
For the mean, add all numbers and divide by the amount of numbers you have:
3 + 5 + 7 + 7 + 23 + 36 / 6
=81/6
= 13.5
Which pair of launch angles below will travel
the same range given the same initial velocity?
A) 30° and 50°
B) 25° and 35°
c) 40° and 50°
D) 30° and 70°
To Find :
Which of the given pair of launch angles below will travel the same range given the same initial velocity.
Solution :
We know, two projectile with same velocity and different angles a and b can have same initial velocity on when the following condition satisfies :
a + b = 90°
Now, putting all the given value in above condition, we get for value 40° and 50° the above condition is true.
Therefore, option c) is correct.
Find the equation of the line that passes through the points (-2, - 5) and (3. – 8).
Answer:
Equation of line that passes through the points is; y= -13x - 31
Step-by-step explanation:
Given coordinates;
(- 2, - 5) and (3. - 8)
Find:
Equation of the line
Computation:
Equation of line that passes through the points is;
y = mx + c
So,
in (- 2, - 5)
-5 = m(-2) + c
-5 = -2m + c ...................Eq1
in (3, - 8)
- 8 = m(3) + c
-8 = 3m + c .....................Eq2
From eq2 + eq1
m = -13
-5 = -2m + c
-5 = -2(-13) + c
-5 = 26 + c
c = -31
So,
y = mx + c
y = (-13)x + (-31)
Equation of line that passes through the points is; y= -13x - 31

One winter, a group of students measured snowfall totals at their school. This chart shows how many inches of snow the students measured each month How much total snowfall did they receive at their school that winter?
month. snowfall
December 4.2
January. 8.9
February. 5.4
Answer: 18.5 inches
Step-by-step explanation:
The total snowfall that the students received at their school that winter will be the addition of the snowfall for each month and this will be:
= December snowfall + January snowfall + February snowfall
= 4.2 + 8.9 + 5.4
= 18.5
The total snowfall is 18.9 inches.

Q = 91°
Step-by-step explanation:
Note how the angles correspond to each of the shapes:
J ---> S
G ---> R
H ---> Q
I ----> P
Since J = 55°, we can see that S is also 55°. With H = 91°, this means that Q is also 91°

Elam can wire a light in 40
minutes. Michael can wire a
light in 60 minutes. How long
would it take them to wire the
light together?
Answer:
24 minutes
Step-by-step explanation:
We use 1/a + 1/b = 1/c
where a and b are the individual times and c is the time together
1/40 + 1/60 = 1/c
Multiply each side by 120c
120c( 1/40 + 1/60 = 1/c)
3c + 2c = 120
5c = 120
Divide each side by 5
5c/5 = 120/5
c = 24
Answer: 24 minutes
Step-by-step explanation: To solve this kind of a problem which is called a work problem, it's important to understand the following idea.
Since Elam can wire a light in 40 minutes, we know that in 1 minute,
Elam can wire 1/40 of the light and in 2 minutes, Elam can wire 2/40 of it.
Therefore, in t hours, Elam can wire t/40 of the light.
The same applies for Michael, in t hours, he can wire t/60 of the light.
So to solve the problem, we use the following formula:
Part of job done by Elam + part of job done Michael = 1 job done
The part of the job done by Elam is t/40 and t/60 for Michael.
So we have t/40 + t/60 = 1.
Now multiply both sides by 120 to get 3t + 2t = 120
or 5t = 120 so t = 24.
So it takes 24 minutes if they work together.
find the solution for x if |6x+8|=32
Answer:
X = 4
Step-by-step explanation:
6x + 8 = 32
6x = 32 - 8
6x = 24
x = 4
the solution is X = 4.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
here, we have,
6x + 8 = 32
6x = 32 - 8
6x = 24
x = 4
hence, the solution is x=4.

Solve for y
4y = 32
Please answer!
Answer:
y = 8
Step-by-step explanation:
4t=32
Divide each side by 4
4y/4 = 32/4
y = 8
Answer: y = 8
Step-by-step explanation:
Firstly, you divide 4 ÷ 4y = 1y or more known as "y" then you do the same thing for the 32 (32 ÷ 4 = 8)
Finally, you write y = 8 and that is your final answer!

Ani was told to write the number four and eight hundredths. She wrote
4.8. Explain whether or not you think Ani is correct. If you think she is not correct, write the number correctly.
Answer:
It would be 4.08, so Ani is wrong writing it as 4.8.
Step-by-step explanation:
So, with this, the number 4 is 4, a single-digit number. Anything below that has a decimal point before it. With the knowledge of there being 8 hundredths, first see this diagram explaining the terms for numbers after the decimal point:
0.1 --> 1 Tenth
0.01 --> 1 Hundredth
0.001 ---> 1 Thousandth
With this, we can see that it will be something of the likes of 4.01-4.09. Since there are 8 Hundredths, it would be 4.08, as 0.01 * 8 = 0.08.
Therefore, she is wrong because she wrote it as 4 and 8 tenths rather than 4 and 8 hundredths.
