A study was done to compare the flu incidence rates at the sart and at the end of winter of a given year. A sample of 100 persons were asked for incidence of flu twice: once at the start and once at the end of winter. Sample data were as follows:
a. Give 99% CI for the difference in flu incidence rates at the start and at the end of winter?
b. Compute a measure of association between flue incidence at the start and at the end of winter?
For each effect, state whether the null hypothesis was rejected or not. Calculate the effect size for the effect of stress
A dentist wanted to determine if a relationship existed between childhood fluoride exposure and cavities. She took a sample of adults in her practice and counted how many cavities each person had in his or her permanent teeth. She also determined how many years of childhood each person was exposed to tap water with fluoride. The minimum value on this variable was 0 and the maximum was 18. Using the data below, an alpha of .05 and a two-tailed test, was there a significant relationship?
