Suppose that the lengths of pregnancies are normally distributed with a mean of 271 days and a standard deviation of 10 days. find the percentage of pregnancies that are longer than 254 days. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%).
Assume that adults have IQ scores that are normally distributed with a mean of 104.8 and a standard deviation 21.9. Find the first quartile Q1, which is the IQ score separating the bottom 25% from the top75%
A medical statistician wants to estimate the average weight loss of people who are on a new diet plan. In a preliminary study, he guesses that the standard deviation of the population of weight loss is about 12 pounds. How large a sample should he take to estimate the mean weight loss to within 3 pounds, with 93% confidence? Sample Size = xxxxxxxxx
The standard deviation of the weights of elephants is known to be approximately 15 pounds. We wish to construct a 95% confidence interval for the mean weight of newborn elephant calves. Fifty newborn elephants are weighted. The sample mean is 244 pounds. The sample deviation is 11 pounds. State the distribution needed. Explain your reasoning. SE
An IQ test is designed so that the mean is 100 and the standard deviation is 10 for the population of normal adults.
