Question

find p value?

An instructor at Arizona State University asked a random sample of six students to record their study times in a beginning calculus course. She then made a table for total hours studied (x) over two weeks and test score (y) at the end of the 2 weeks. The results are shown in the accompanying table. Presuming that the assumptions for regression inferences are met, decide at the specified significance level whether the data provide sufficient evidence to conclude that the predictor variable is useful for predicting the response variable. Use α = 0.05. 12 14 16 15 20 84 84 80 81 74 Time, x Score, y y = 94.36 -0.92x, x₁ = 85, Ex=1285, b₁ = -0.92, and s₂ = 1.9350 What are the hypotheses for the test? A. Ho: P₁ = 0 and H₂: B₁ #0 B. Ho: B₁0 and H₂: B₁ >0 O C. Ho: B₁ = 0 and H₂: B₁ <0 D. Ho: B₁ #0 and H₂: B₁ = 0 What is the test statistic? 8 85 t= (Round to two decimal places as needed.)
