Use a t-distribution to answer this question. Assume the samples are random samples from distributions that are reasonably normally distributed, and that a t-statistic will be used for inference about the difference in sample means. State the degrees of freedom used. Find the proportion in a t-distribution less than -1.4 if the samples have sizes n1

The proportion in a t-distribution less than -1.4 is 0.095 and this can be determined by using the given data.

Given :

The degree of freedom is given by:

df = Min.(11 , 11)

df = 11

Now, compute the proportion in t-distribution:

                      = 0.095

The proportion in a t-distribution less than -1.4 is 0.095 and this can be determined by using the given data.

The degrees of freedom is 11.

The proportion in a t-distribution less than -1.4 is 0.095.

Step-by-step explanation:

The complete question is:

Use a t-distribution to answer this question. Assume the samples are random samples from distributions that are reasonably normally distributed, and that a t-statistic will be used for inference about the difference in sample means. State the degrees of freedom used. Find the proportion in a t-distribution less than -1.4  if the samples have sizes 1 = 12 and n 2 = 12 . Enter the exact answer for the degrees of freedom and round your answer for the area to three decimal places. degrees of freedom = Enter your answer; degrees of freedom proportion = Enter your answer; proportion

Solution:

The information provided is:

Compute the degrees of freedom as follows:

Thus, the degrees of freedom is 11.

Compute the proportion in a t-distribution less than -1.4 as follows:

*Use a t-table.

Thus, the proportion in a t-distribution less than -1.4 is 0.095.
