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.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
