Wassamatta University offers supplemental instruction (SI) for introductory chemistry students three times a week. The table below shows the number of SI visits during the semester for a sample of students along with each student's final class average. Use technology to compute a p-value and use it to determine whether the regression equation is useful for making predictions about the benefit of attending SI. Test at the 5% significance level with the hypotheses H
0: β
1 = 0 and H
a: β
1 ≠ 0.
◦ p = 0.2633. Since p > α, reject the null hypothesis H
0: β
1 = 0. The regression equation is useful for making predictions.
◦ p = 0.2529. Since p > α, do not reject the null hypothesis H
0: β
1 = 0. The regression equation is not useful for making predictions.
◦ p = 0.04229. Since p < α, reject the null hypothesis H
0: β
1 = 0. The regression equation is useful for making predictions.
◦ p = 0.0325. Since p < α, do not reject the null hypothesis H
0: β
1 = 0. The regression equation is not useful for making predictions.
first day of my chemistry class.. this is what the teacher had to say
Researchers have found that science instruction can be quite effective in grades 4 to 7.
Common Blood Chemistry Tests
An example of continuous variation: biology students organized according to height.
