How many cars must be randomly selected and tested in order to estimate the mean braking distance of registered cars in the United States. We want 99% confidence that the sample mean is within 2 feet of the population mean, and the population standard deviation is know to be 7 feet.
hat is sampling error? Could the value of the sampling error be zero? If it were zero, what would this mean? List the reasons for sampling. Give an example of each reason for sampling.
Plasma glucose levels are used to determine the presence of diabetes. Suppose the mean in (plasma-glucose) concentration (mg/dL) in 35-44 year olds is 4.86 with standard deviation = 0.54.
What is the 90% confidence interval estimate of the difference between two population means.
Half of the 1000 emloyees were involved in some type of exercise. What is the probability that an employee will have a cold next year?
Suppose the population mean is 50.6 pounds with a population standard deviation of 1.62 pounds. Suppose we take thousands of samples with a sample size of 5.
