A researcher wants to study the performance of high school students of district W in the mathematics final exam. To study the performance, he uses the marks scored by the students in mathematics M as a function of the average number of hours spent by the student on practice H and number of days the student attended the mathematics class in school D. For his study, he selects a random sample of 150 high school students and estimates the following regression function: M= 10.25 + 2.25H +2.75D. The researcher wants to test whether or not changing the average number of hours spent by the student on practice has a statistically significant impact on the marks scored by the students in mathematics. Keeping the other variables constant, the null and the alternative hypotheses of the test conducted by the researcher are Ho B =0 vs. H, B, #0. The test statistic for the test is 2.50 Therefore, the p-value of the test is (Round your answer to two decimal places.) v the null hypothesis. If the study uses two-sided test with the 5% significance level, then the p-value suggests that we The researcher now wants to test whether or not increasing the number of days the student attended the mathematics class in school significantly improves the marks scored by the students in mathematics. Keeping the other variables constant, the researcher wants to calculate the p-value for the test Ho B, =0 vs. H, B >0. The test statistic for this test is 2.55.

Question
A researcher wants to study the performance of high school students of district Win the mathematics final exam. To study the performance, he uses the marks scored by the students in mathematics M as a function of the average number of hours spent by the student on practice H and number of days the student attended the mathematics class in school D. For his study, he selects a random sample of 150 high school students and estimates the following regression function: M= 10.25 + 2.25H+2.75D. The researcher wants to test whether or not changing the average number of hours spent by the student on practice has a statistically significant impact on the marks scored by the students in mathematics. Keeping the other variables constant, the null and the alternative hypotheses of the test conducted by the researcher are H, B, - 0 vs. H, B, #0. The test statistic for the test is 2.50. Therefore, the p-value of the test is (Round your answer to two decimal places.) v the null hypothesis. If the study uses two-sided test with the 5% significance level, then the p-value suggests that we The researcher now wants to test whether or not increasing the number of days the student attended the mathematics class in school significantly improves the marks scored by the students in mathematics. Keeping the other variables constant, the researcher wants to calculate the p-value for the test Ho B2 =0 vs. H, 2> 0. The test statistic for this test is 2.55.
