A unit increase in gender will result in decrement of -52.73 in wage provided holding all other parameter constant.
What is parameter?
A parameter is a piece of information that an equation passes on. In terms of statistics, it means something different. In contrast to statistics, which only provide information about a small portion of the population, this value provides information about the entire population.
A parameter is constant because it was determined by surveying everyone (or everything). The average age of the students in your class, for instance, might be of interest to you. Maybe after asking everyone, you discovered that the average age was 25. Given that you polled the entire class, that qualifies as a parameter. Let's say you were curious about the median age of your grade or year.

Step 1: We need to test the given hypothesis.
We can take x1- x2 to represent the difference between the jumping and relaxed times.
[tex]H0: u1 = u2\\H1: u1 \neq u2[/tex]
Step 2: Simplification
We need to find the mean and standard deviation of both samples.
[tex]u1 = 32.375, s1 = 9.620477\\u2 = 30.625, s2 = 8.331309[/tex]
The differences between the jumping and relaxed times are calculated:
[tex]5, 7, 2, 1, -2, 2, 2, -3[/tex]
The number of differences is ∑(8, i-1) = [tex](d_{i} - \alpha ) ^{2}[/tex] = 75.5
Standard deviation differences are:
[tex]\sqrt{\frac{75.5}{7} }[/tex] = 3.284
The standard error is SE = 1.161
Using this, we can find the value of the test statistic t:
[tex]t = \frac{u1 - u2}{SE}[/tex] = 1.507
Using this and the graph, we get that the p value is 0.17554.
Therefore, since p-value is greater than α = 0.05, we cannot reject the hypothesis H0, and we can conclude that it is insufficient evidence to conclude that the average difference is not zero.
Since p-value is greater than α = 0.05, we cannot reject the hypothesis H0, and we can conclude that it is insufficient evidence to conclude that the average difference is not zero.

solve the following trigonomic equation for 0 < theta < 2pi
cos(theta) * csc(theta) - 2cos(theta) = 0
pls help
Answer:
To solve the given trigonometric equation, we can start by isolating the cos(theta) term on one side of the equation. We can do this by dividing both sides of the equation by csc(theta):cos(theta) * csc(theta) - 2cos(theta) = 0
cos(theta) * csc(theta) / csc(theta) - 2cos(theta) / csc(theta) = 0 / csc(theta)
cos(theta) - 2cos(theta) / csc(theta) = 0Next, we can combine like terms on the left side of the equation:cos(theta) - 2cos(theta) / csc(theta) = 0
-2cos(theta) / csc(theta) + cos(theta) = 0
(1 - 2 / csc(theta)) cos(theta) = 0Since cos(theta) cannot be equal to 0 (because the angle theta is between 0 and 2pi), the only solution to this equation is:1 - 2 / csc(theta) = 0
1 = 2 / csc(theta)
csc(theta) = 2This means that the value of csc(theta) is equal to 2. To find the value of theta, we can use the inverse cosecant function (arcsec) to solve for theta:theta = arcsec(2)The value of arcsec(2) is approximately 1.047198, which is the solution to the given equation for theta.Note that this is just one solution to the equation, as there may be other solutions for theta depending on the values of the trigonometric functions. It is important to check that the solution falls within the given range of 0 < theta < 2pi.

Write an expression for the sequence of operations described below.
Subtract the quotient of 3 from h
Do not simplify any part of the expression.
Answer:
h - (3/h)
Step-by-step explanation:
The expression for the sequence of operations described is h - (3/h).
To evaluate this expression, we would first need to divide 3 by h to find the quotient, and then subtract that quotient from h. This would give us the final result of the sequence of operations.
For example, if h = 10, we would first divide 3 by 10 to get 0.3. We would then subtract 0.3 from 10 to get 9.7. This would be the final result of the sequence of operations.
In general, the expression h - (3/h) can be used to represent any sequence of operations that involves subtracting the quotient of 3 from h. The value of h can be any number, and the final result of the sequence of operations will depend on the specific value of h that is used.

If 15% of college students own a television, and 10% of college students own a stereo, and 2% of college students own both a television and a stereo, then the percent of college students that own either a television or stereo is 23%.
True
False
The percentage of students who owns either a television or stereo is given by the set formula P ( A ∪ B ) = 23 %
What is Set Theory Formula?
The set formula is given in general as n(A∪B) = n(A) + n(B) - n(A⋂B), where A and B are two sets and n(A∪B) shows the number of elements present in either A or B and n(A⋂B) shows the number of elements present in both A and B.
The union of two sets is a new set that contains all of the elements that are in at least one of the two sets
The intersection of two sets is a new set that contains all of the elements that are in both sets
The equation is n(A∪B) = n(A) + n(B) - n(A⋂B)
Given data ,
Percentage of college students who owns a television or stereo be represented as = P ( A ∪ B )
Percentage of college students who owns a television is P ( A ) = 15 %
Percentage of college students who owns a stereo is P ( B ) = 10 %
Let the percentage of college students who owns a television and stereo is P ( A ∩ B ) = 2 %

P (A∪B) = P ( A ) + P ( B ) - P ( A ⋂ B )
Substituting the values in the equation , we get
P (A∪B) = 15 + 10 - 2
On simplifying the equation , we get
P (A∪B) = 25 - 2
P (A∪B) = 23 %
Therefore , the value of P (A∪B) is 23 %

Ryan delivers flowers to two customers. He drives for 12 minutes at an average speed of
40 miles per hour to reach his first customer. He then drives for 15 minutes at an average
speed of 50 miles per hour to reach his second customer. During the 27 minutes of driving
time, how many total miles does Ryan drive?
Answer:20.5 miles
Step-by-step explanation:
the formula for distance, rate (speed), and time is
Distance=rate×time
D=40 (this is the speed he was going for the first customer) × [tex]\frac{12}{60}[/tex] (time)
the time is 12/60 because we the speed was in miles per HOUR and the time was in miles per MINUTE. To convert minutes to hours, we divide by 60.
D=40× [tex]\frac{12}{60}[/tex]
D=48/6
D=8 miles
Second trip:
D= 50×[tex]\frac{15}{60}[/tex]
D=50×[tex]\frac{1}{4}[/tex] (15/60 simplified is 1/4)
D= 12.5 miles
ANSWER: 8 miles + 12.5 miles = 20.5 miles
