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 b1=4.6 and Sb1=1.9. 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, β1.

Please help. Thanks!

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, = 3.7 and S, = 1.3. 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, B1. a. What are the hypotheses to test? O A. Ho: B1 s0 H;: B, >0 O B. Ho: B1 +0 H;: B, = 0 С. Но В120 H;: B, <0 D. Ho: B1 =0 H;: B1 #0 tSTAT = (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.) c. What statistical decision should you make? A. Since tsTAT is greater than the upper critical value, do not reject the null hypothesis. B. Since tSTAT is between the two critical values, reject the null hypothesis. C. Since tsTAT is greater than the upper critical value, reject…

A sample of n = 20 scores is transformed in to z-scores. The mean for the 20 z-scores is ____? If a researcher reports t(18) = 1.30, p > .05 for a two-sample independent-measures experiment, the results were significant. T or F?
