Question
Not understanding how they’re getting the p value
t value for A study of traits in people was conducted. A rating score was determined for each in a sample of people of a large Independent university. For one portion of the study, the researcher modeled a person's score (y) as a function of age, gender, variable education, and income. Data on n= 193 people yielded the results in the table to the right. Complete parts a through c. p-value Họ: B; = 0 Age (x1) Gender (x2) 0.10 >0.10 2.05 <0.10 Education (x3) Income (x4) 0.52 >0.10 - 0.55 >0.10 Overall model: R = 0.11, F = 5.81 (p-value <0.01) a. Conduct a test of overall model utility. Use a = 0.10. What are the null and alternative hypotheses? A. Ho: B1 = B2 = B3 =B4 = 0 O B. Ho: At least one ß, #0 Ha: Po = B1 = B2 = ß3 = B4 = 0 Ha: At least one B, #0 O C. Ho: At least one ß, #0 O D. Ho: Po = B1 = B2 = B3 = B4 = 0 Ha: At least one B; # 0 Ha: B1 = B2 = B3 = B4 = 0 What is the test statistic? F = 5.81 (Round to two decimal places as needed.) What is the p-value? p= 0.0000 (Round to four decimal places as needed.)
