Answer: The sampling distribution of the difference in sample proportions is approximately normal
Step-by-step explanation:
Given that :
Random sample of deer from one region = 200
p = 0.06
1 - p = 1 - 0.06 = 0.94
Random sample of deer from other region = 197
p = 8.6% = 0.086
1 - p = 1 - 0.086 = 0.914
For an approximately normal distribution :
np ≥ 10
n(1 - p) ≥ 10
(200) (0.06) = 12
(200) (0.94) = 188
(197)(0.086) = 16.942
(197)(0.914) = 180.058
Since all conditions are met :
Then, the sampling distribution of the difference in sample proportion is approximately normal.

Answer:
5
Step-by-step explanation:
Q is asking how many (1/3)s are in (15/8):
(15/8) / (1/3)
(to divide fractions, flip the second fraction over and then multiply)
(15/8) * (3/1)
(15 * 3) / (8*1)
45/8
=5.625

A store sells comic books. Each comic book costs the same amount. During a sale, the store reduces the price of each comic book by 1.45. Miguel
spends $12.88 on 2 comic books at the sale price.
What was the price of I comic bbok before the sale? Enter the answer in the box.
Answer:
$7.89
Step-by-step explanation:
Given that Miguel spends $12.88 on 2 comic books then the amount spent on 1 book given that the prices of the books are equal will be
= $12.88/2
= $6.44
Given that the store reduced the price of each comic book by $1.45 then the price P of 1 comic book before the sale
P = $6.44 + $1.45
= $7.89
The cost of 1 comic book before the sale ( which is before the reduction in price) is $7.89

A basketball player has a 0.6 probability of making a free throw. What is his probability of making two consecutive free throws. Remember free throws are independent of each other. Show work and solve.
Answer:0.36
Step-by-step explanation:
Given
Probability of a free throw =0.6
It is given that the two throws are independent of each other
So, the Probability of making two consecutive throws
[tex]P=\text{Probability of first throw}\times \text{Probability of second throw}\\P=0.6\times 0.6=0.36[/tex]

Find the solutions to the equation below.
Check all that apply.
9x^2 - 81 = 0
A. X=-81
B. x= 9 C.
x= 3
D. x= -3
E. X=-9
F.x=1
Step-by-step explanation:
Use the quadratic formula to find the solutions.
−b±√b2−4(ac)2a-b±b2-4(ac)2a
Substitute the values a=9a=9, b=0b=0, and c=−81c=-81 into the quadratic formula and solve for xx.
x=±3x=±3
The final answer is the combination of both solutions.
x=3,−3x=3,-3

Jim’s soccer team has a record of 12 wins and 8 losses. Which team below has the same rate of wins and losses?
Answer:
a volleyball team with 9 wins and 6 losses
Step-by-step explanation:
Jim’s soccer team has a record of 12 wins and 8 losses.Hence when divded
the answer is 1.5 or the same as 3/2 .Hence all we need need to do is find the
answer that is the same as 1.5.
Hence the answer is B a volleyball team with 9 and 6 losses.I know it's right because whenever 9 and 6 divdied they make 1.5.hence this answer is right
n a box of 12 tape measures, there is one that does not work. Employees take a tape measure as needed. The tape measures are not returned, once taken. You are the 8th employee to take a tape measure. Is this a binomial experiment?
a. Yes, the probability of success is one out of 12 with 8 selected.
b. No, the probability of getting the broken tape measure changes as there is no replacement.
c. Yes, you are finding the probability of exactly 5 not being broken.
d. No, binomial does not include systematic selection such as "eighth".
Answer:
b. No, the probability of getting the broken tape measure changes as there is no replacement.
Step-by-step explanation:
For each tape measure, there are only two possible outcomes. Either it is broken, or it is not, which means that the first condition for the binomial distribution is respected.
However, the tapes are not returned to the box, which means that in each trial, the probabilities of getting the tape with defect changes, which means that the binomial distribution cannot be used. So option b is the correct answer
