Question

Please answer all questions fully.

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, = 3.6 and Sp,
= 1.4.
a. What is the value of tsTAT?
b. At the a = 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 the population slope, B,.
a. What are the hypotheses to test?
A. Ho: B1 20
H;: B, <0
O B. Ho: B1 +0
H;: B, = 0
C. Ho: B1 = 0

D. Ho: B, s0
H4: B, >0
tSTAT = 0 (Round to two decimal places as needed.)
b. The lower critical value is
The upper critical value is
(Round to four decimal places as needed.)
