Sleep Time A person read that the average number of hours an adult sleeps on Friday night to Saturday morning was 7.2 hours. The researcher feels that college students do not sleep 7.2 hours on average. The researcher randomly selected 15 students and found that on average they slept 8.3 hours. The standard deviation of the sample is 1.2 hours. At a=0.05, is there enough evidence to say that college students do not sleep 7.2 hours on average? Assume that the population is approximately normally distributed. Use the critical value method and tables.

A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 99.3-cm and a standard deviation of 1.5-cm. For shipment, 25 steel rods are bundled together.Find P27, which is the average length separating the smallest 27% bundles from the largest 73% bundles. P27 =
The average amount of money that each customer spends at a particular bar is $27.84 with a standard deviation of $7.32. The owner of the bar is attempting to increase sales. The owner decides that playing live music will increase sales. The owner tests her theory by getting her son’s garage band to play one night at the bar for a random sample of 64 of her customers and then records the check total for each customer who was there while the band was playing. The customers who were there while the band was playing spent an average of $24.56. Conduct a one-tailed hypothesis test with a significance level of 5% to determine if customers spent more money when the live music was playing.
2.8 In China, four-year-olds average three hours a day unsupervised. Most of the unsupervised children live in rural areas, considered safe. Suppose that the standard deviation is 1.5 hours and the amount of time spent alone is normally distributed. We randomly select one Chinese four-year-old living in a rural area. We are interested in the amount of time the child spends alone per day. What percent of the children spend over ten hours per day unsupervised? Answer: %

A machine used to fill gallon-sized paint cans is regulated so that the amount of paint dispensed has a mean of 128 ounces and a standard deviation of 0.40 ounce. You randomly select 45 cans and carefully measure the contents. The sample mean of the cans is 127.9 ounces. Does the machine need to be reset? Explain your reasoning. it is that you would have randomly sampled 45 cans with a mean equal to 127.9 ounces, because it within the range of a usual event, namely within of the mean of the sample means.
