Textbook Question
Chapter 13.4, Problem 24E
An automobile dealer conducted a test to determine if the time in minutes needed to complete a minor engine tune-up depends on whether a computerized engine analyzer or an electronic analyzer is used. Because tune-up time varies among compact, intermediate, and full-sized cars, the three types of cars were used as blocks in the experiment. The data obtained follow.
| Analyzer | |||
| Computerized | Electronic | ||
| Compact | 50 | 42 | |
| Car | Intermediate | 55 | 44 |
| Full-sized | 63 | 46 |
Use α = .05 to test for any significant differences.

Suppose a researcher is interested inthe effectiveness in a new childhood exercise program implemented in a SRS of schools across a particular county. In order to test the hypothesis that the new program decreases BMI (Kg/m2), the researcher takes a SRS of children from schools where the program is employed and a SRS from schools that do not employ the program and compares the results. Assume the following table represents the SRSs of students and their BMIs.

Student control group

A) Assuming that all the necessary conditions are met (normality, independence, etc.) carry out the appropriate statistical test to determine if the new exercise program is effective. Use an alpha level of 0.05. Do not assume equal variances.B) Construct a 95% confidence interval about your estimate for the average difference in BMI between the groups.
I’m interested in seeing whether or not online supplementary material helps students achieve higher grades in statistics. I assign 10 students into a class using an online textbook resource whereas 10 separate students are assigned into a class using just the textbook. I record their final course average (final course grade). Using the following data (testing at an alpha of .05), assess whether those that used the online resources + textbook (group 1) did better than those just using the textbook (group 2).

In one experiment, the cross produced 89 glandular and 36 glandless plants. Use goodness-of-fit tests (at alpha= 0.10) to determine whether the data is consistent with a) the 11:5 theory, ar b) the 13:3 theory.arrow_forward
