e) Suppose a sample of 3 books is chosen at random form this population. i. What is the probability that the mean number of pages of the 3 books is 20% more than the population mean?
Suppose you choose 2 books(1Malay and1English)that you are planning to read. Thus, there will be a total of 
number of books, where is the number of team members. Assume that this is the size of population that is approximately normally distributed with mean and standard deviation .

A simple random sample of size 14 has mean 3.67 and standard deviation 1.75. The population is approximately normally distributed. Construct a 99% confidence interval for the population mean. 1. The parapmeter is the population (choose one) mean, standard deviation, variable, proportion 2. The correct method to find the confidence interval is the (choose one) z, t, chi square method

Suppose that the lifetimes of light bulbs are approximately normally distributed. A random sample with 38 light bulbs was obtained with a mean of 60 hours and a standard deviation of 4.5 hours. With this information, answer the following questions. To estimate the population mean, what is the Standard Error? To estimate the population mean at 95% C.L., what is the Margin of Error? At a 96% C.L., if the researcher wants to limit the margin of error within 0.5...
