The crisis in the real estate market caused the listing prices of homes in certain areas to fall from previous years. A real estate office would like to sample 48 new listings randomly to test the hypothesis that the current listing price average is less than $244,000, the average in the previous year. Assume the standard deviation for the price of homes in this market is $45,000. Complete parts a through d below. a. Explain how Type I and Type II errors can occur in this hypothesis test. A Type I error can occur if the average listing price is rejected. ▼$244,000 and the null hypothesis is rejected. A Type II error can occur if the average listing price is $244,000 and the null hypothesis is not

To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles, a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B. The mean braking distance for Make A is 43 feet. Assume the population standard deviation is 4.6 feet. The mean braking distance for Make B is 46 feet. Assume the population standard deviation is 4.5 feet. At α=0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles? Assume the samples are random and independent, and the populations are normally distributed. The critical value(s) is/are Find the standardized test statistic z for μ1−μ2.
Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. A simple random sample of 2525 filtered 100 mm cigarettes is obtained, and the tar content of each cigarette is measured. The sample has a mean of 19.419.4 mg and a standard deviation of 3.143.14 mg. Use a 0.050.05 significance level to test the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.121.1 mg, which is the mean for unfiltered king size cigarettes.
