The answer is 30. You just multiply 51 by (10/17)
Answer:
a. n=4148
b. n=3909
c. The sample size is smaller if a known proportion from prior study is used. The difference in sample sizes is 239
Step-by-step explanation:
a. For sample where no preliminary estimate is given, the minimum sample size is calculated using the formula:

Where:
Margin of error
is the assumed proportion
#Let p=0.5, substitute in the formula to solve for n:

Hence, the minimum sample size is 4148
b. If given a preliminary estimate p=0.38, we use the same formula but substitute p with the given value:

Hence, the minimum sample size is 3909
c. Comparing the sample sizes from a and b:

Hence, the actual sample size is smaller for a known proportion from prior a prior study.
Answer:
(-38) / (-8)
equals 4.75
a negative divided by a negative is always a positive

Step-by-step explanation:
Answer:
1/6 cup of milk
Step-by-step explanation:
1/2 (amount of milk)- 1/3 (amount of water)
1/2 = 3/6
1/3 = 2/6
3/6 - 2/6 = 1/6
