In a 1993 study, researchers took a sample of people who claimed to have had an intense experience with an unidentified flying object (UFO) and a sample of people who did not claim to have had such an experience (Spanos et al., 1993). They then compared the two groups on a wide variety of variables, including IQ. Suppose you want to test whether or not the average IQ of those have had such a UFO experience is higher than 100.
The sample mean IQ was 101.6, the sample standard deviation was 8.9, and the sample size was 25. Assume the population is normally distributed.
a) H_0: mu = , H_a: mu 100
b) Is the CLT for means valid?
c) Calculate the test statistic. (4 decimal places for all calculations)
d) Calculate the p value as best we can (use the formatting from question 1)

Researchers have suggested that personality type is related to heart disease. Specifically, type A people, who are competitive, driven, pressured, and impatient, are more prone to heart disease. On the other hand, type B individuals, who are less competitive and more relaxed, are less likely to have heart disease. Suppose than an investigator would like to examine the relationship between personality type and disease. For a random sample of individuals, personality type is assessed with a standardized test. These individuals...
