The heights (in inches) of adult males in the United States are believed to be normally distributed with a mean of 69.50 inches. The mean height of a random sample of 35 American adult males was found to be = 70.78 inches with a standard deviation (sx) of 3.95. A: What type of test should you conduct? One-sample t test, Independent 2-sample t test, Paired sample t test? B. Should you reject or retain the null hypothesis using an alpha level of 0.05? C: Construct a 95% confidence interval around the relaxation group’s mean. D: Calculate a Cohen’s d effect size value.
