Based upon historical data, it is known that 8% of 12-egg cartons contain at least one broken egg. A grocerystore manager would like to carry out a simulation to estimate the number of cartons, in a sample of 10, thatwould contain at least one broken egg. She assigns the digits to the outcomes:01-08 = carton contains a broken egg09-99, 00 = carton does not contain a broken eggHere is a portion of a random number table.1 31645 03495 96193 108982 67940 85019 98036 982523 21805 26727 73239 5392903648 93116 98590 100835 71716 46584 35453 98153Beginning at line 1, carry out one trial of this simulation.

In the Star and Tribune newspaper, there is an article entitled "1 in 8 school buses fail tests." The article says that the overall statewide proportion of school buses that fail safety tests is 9%. However, one bus company has a higher rate of over 12%. Assume that we want a new estimate for the statewide proportion of school buses that fail the safety inspection. We take a sample of 500 buses and find that 90 buses fail the safety inspection. Based on the new sample data, I construct this 90% confidence interval estimate for p: 152 < p < .208. Explain what this confidence interval means. O I am 90% sure that the number of buses that fail the inspection is between.152 and .208. O I am 95% sure that the true proportion of buses that fail the inspection is between .152 and .208. O I am 90% sure that the proportion of buses in this sample that fail the inspection is between .152 and .208. O I am 90% sure that the true proportion of buses that fail the inspection is between .152 and .208.

Thirty-two percent of all Americans drink bottled water more than once a week (Natural resources Defense Council, December 4, 2015). Suppose you have been hired by the Natural Resources Defense Council to investigate bottled water consumption in St. Paul. You plan to select a sample of St. Paulites to estimate the proportion who drink bottled water more than once a week. Assume the population proportion of St. Paulites who drink bottled water more than once a week is 0.32, the same as the overall proportion of Americans who drink bottled water more than once a week. E(p bar) = Based upon a sample of 540 St. Paulites, what is the probability that the sample proportion will be within 0.08 of the population proportion (to 4 decimals). Probability = Suppose you select a sample of 230 St. Paulites. Show the sampling distribution of p bar (to 4 decimals). Based upon a smaller sample of only 230 St. Paulites, what is the probability that the sample proportion will be within 0.08 of the…

A vaccine to prevent a severe virus was given to children within the first year of life as part of a drug study. The study reported that of the 3456bchildren randomly assigned the vaccine, 58 got the virus. Of the 1606 children randomly assigned the placebo, 46 got the virus. a. Find the sample percentage of children who caught the virus in each group. Is the sample percentage lower for the vaccine group, as investigators hoped? b. Determine whether the vaccine is effective in reducing the chance of catching the virus, using a significance level of 0.01.The first few steps of the hypothesis-testing procedure are given. Complete the procedure.
