Cell Phone Lifetimes A recent study of the lifetimes of cell phones found the average is 23.2 months. The standard deviation is 3.1 months. If a company provides its 33 employees with a cell phone, find the probability that the mean lifetime of these phones will be less than 23.8 months. Assume cell phone life is a normally distributed variable, the sample is taken from a large population, and the correction factor can be ignored. Use a TI-83 Plus/TI-84 Plus calculator. Round your answer to at least four decimal places. P(X<23.8)=

More time on the Internet: A researcher polled a sample of 1097 adults in the year 2010, asking them how many hours per week they spent on the Internet. The sample mean was 9.42 with a standard deviation of 13.23 . A second sample of 1031 adults was taken in the year 2012 . For this sample, the mean was 10.63 with a standard deviation of 14.47. Assume these are simple random samples from populations of adults. Can you conclude that the mean number of hours per week spent on the Internet increased between 2010 and 2012? Let u1 denote the mean number of hours spent on the Internet in 2010 . Use the a=0.05 level and the p-value method to solve. State the p-value _______________-
Españiol A scientist has read that the mean birth weight of babies born at full term is 7.4 pounds. The scientist has good reason to believe that the mean birth weight of babies born at full term, µ, is different from this value and plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 7.8 pounds and the standard deviation to be 1.8 pounds. Based on this information, complete the parts below. (a) What are the null hypothesis H. and the alternative hypothesis H, that should be used for the test? Ho :0 O
