Chapter 6, Section 4-D, Exercise 186 Incorrect 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 n30 and n2 -40 Enter the exact answer for the degrees of freedom and round your answer for the area to three decimal places 68 degrees of freedom 68 proportion =

Explanation / Answer

here degree of freedom =mimimum (n1,n2)-1

theefore degree of freedom =minimum(30,40)-1=29

for 29 df and above test statsitic p value =0.086
