A teacher and her eight introductory statistics students to record the total amount of time they spent studying for a particular test. The amounts of study time (in hours) and the resulting test greased y are given below x 2 1 1.5 0.5 1 3 0 2 y 92 81 82 68 85 96 48 74 Suppose we want to find out if the number of hours studied helps predict the grade earned on this statistics test. Perform a significance test at the 0.5 significance level.

Step 1
State the null hypothesis (H0) and the alternative hypothesis (H1). H0: There is no relationship between the number of hours studied and the grade earned on the test (i.e., the slope of the regression line is 0). H1: There is a relationship between the number of Show more…

The following data gives the number of hours 10 students spent studying and their corresponding grades on their midterm exams. Hours Spent Studying 0 0.5 1.5 2 2.5 3 3.5 4 4.5 5.5 Midterm Grades 63 66 69 75 78 81 84 87 90 96 It the data is statistically significant at the 0.05 level, find the estimated value of y when x = 6. Round your answer to three decimal places.

⦁ A math teacher wants to determine the effectiveness of her statistics lesson. She gives a simple skills test to nine students before the start of class (a pre-test) and the same skills test to the same students at the end of class (a post-test). Here’s the data (with some calculations) pre test post test 78 80 67 69 56 70 78 79 96 96 82 84 84 88 90 92 87 92 ⦁ Was there a change in student performance from the Pre-test to the Post-test? Level of significance 5% ⦁ Write a brief report explaining your findings

A college statistics professor is interested in the relationship among various aspects of students' academic behavior and their final grade in the class. She found a significant relationship between the number of hours spent studying statistics per week, the number of classes attended per semester, the number of assignments turned in during the semester, and the student's final grade. This relationship is described by the multiple regression equation $y^{\prime}=-14.9+0.93359 x_{1}+$ $0.99847 x_{2}+5.3844 x_{3} .$ Predict the final grade for a student who studies statistics 8 hours per week $\left(x_{1}\right)$, attends 34 classes $\left(x_{2}\right),$ and turns in 11 assignments $\left(x_{3}\right)$
