Question

. 1.6 You are testing the null hypothesis that there is no linear relationship between two variables X and Y. From your sample of n = 18, you determine that b.-4.1 and S a. What is the value of tSTAT? b. At the 0.05 level of significance, what are the critical values? c. Based on your answers to (a) and (b), what statistical decision should you make? d. Construct a 95% confidence interval estimate of te populaton slope, - a. What are the hypotheses to test? tsm"(Round to two decmal places as needed ) b. The lower critical value is The upper critical value is (Round to four decimal places as needed.)

Explanation / Answer

sol:

hypothesis to test

Ho:slope=0

beta1=0

alternative hypothesis:

H1: beta1 not = 0

optionD

tSTAT=slope/stddeviation

=4.1/1.6=2.56

df=degrees of freedom=n-2=18-2=16

The P-Value is .020975.

The result is significant at p < .05.

Reject null hypothesis
