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? Years of fluoride Number of cavities 0 10 18 1 2 7 12 3 3 4 10 5 M = 7.5s =6.98 M = 5.00s = 3.16

A random sample of 8080 eighth grade students' scores on a national mathematics assessment test has a mean score of 265265. This test result prompts a state school administrator to declare that the mean score for the state's eighth graders on this exam is more than 260260. Assume that the population standard deviation is 3030. At alphaαequals=0.140.14, is there enough evidence to support the administrator's claim? Complete parts (a) through (e).
