And if we use the permutation formula given by:

And replacing we got:

Step-by-step explanation:
For this problem we want to find the following expressionÑ

And if we use the permutation formula given by:

And replacing we got:

Quotient refers to division:
(8/v)² ⇒ (8/v)(8/v) = 8*8 / v*v = 64/v²
When you raise a fraction to a power, you multiply the fraction by itself according to the power raised.
Then, do the usual steps of multiplying fractions.
1) multiply numerators.
2) multiply denominators
3) simplify fraction produced.
Answer:
Step-by-step explanation:
Given that a researcher is using a repeated-measures design to test for mean differences among four treatment conditions.
The data for this study consist of 10 scores in each treatment.
We have to find the total subjects who participated in the study.
Each treatment has 10 scores
No of treatments = 4
Hence subjects participated in the study
= no of treatment x no of subjects
= 
Answer:
Step-by-step explanation:
The question is incomplete. The complete question is:
An insurance company reported that, on average claims for a certain medical procedure are $942. an independent organization constructed a 95% confidence interval of ($930, $950) for the average amount claimed for the particular medical procedure. what conclusion best evaluates the truthfulness of the number reported by the insurance company?
a) with 95% certainty, the average claim for this medical procedure is $942.
b) with 95% certainty, the average claim for this medical procedure is not $942.
c) the confidence interval is consistent with an average claim of $942 for this medical procedure
Solution:
Confidence interval is used to express how confident we are that the population parameter that we are looking for is contained in a range of given values. Looking at the given confident interval, the lower limit is $930 and the upper limit is $950. We can see that the population mean, $942 lies within these values. The correct option would be
c) the confidence interval is consistent with an average claim of $942 for this medical procedure
