Grant has a sample of 36 rats in his study. If he conducts a single-sample t test, what is the value of the degrees of freedom? 37

6

36

35

35

Step-by-step explanation:

Given

Sample of rat

Population = 36

Required

Find the degree of freedom.

Given that the sample is a single-sample t test;

A single-sample t test has just one parameter has its estimate;

And its degree of freedom is calculated as thus;

Where df represents the degree of freedom and n represents the sample size;

By substituting n = 36;

Hence, the degree of freedom of the sample of 36 rats for a single-sample t test is 35

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
