A sketch must accompany the solutions for question 3. 1. Assume that body temperatures of healthy adults are normally distributed with a mean of 98.2°F and a standard deviation of 0.62°F. Suppose you collect a sample of size n healthy adults. Would you be more likely to obtain a sample mean of 97.9 or less if n= 25 or if n = 100? Explain. (1-P) 2. 2. How much do Americans sleep each night? Based on a random sample of 1120 Americans 15 years of age or older, the mean amount of sleep per night is 8.17 according to the American Time Use Survey conducted by the Bureau of Labor Statistics. Assuming the population standard deviation for amount of sleep per night is 1.2 hours, construct and interpret a 95% confidence interval for the mean amount of sleep per night of Americans 15 years of age or older. mean calorie intake of males 20 to According to the U.S. Department of Agriculture, the dord deviation of 72.8. 3.
