5. According to data from the Environmental Protection Agency, the averagedaily water consumption for a household of four people in the United Statesis approximately at least 243 gallons. Suppose a state agency plans to testthis claim using an alpha level equal to 0.05 and a random sample of 100households with four people.a) State the appropriate null and alternative hypotheses.b) Calculate the probability of committing a Type II error if the truepopulation mean is 230 gallons. Assume that the population standarddeviation is known to be 40 gallons.

Solution: Given information: n= 100 Sample size μo= 243 Population mean under Ho μ= 230 True mean…

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 safety administration conducted crash tests of child booster seats for cars. Listed below are results from those tests, with the measurements given in hic (standard head injury condition units). The safety requirement is that the hic measurement should be less than 1000 hic. Use a 0.01 significance level to test the claim that the sample is from a population with a mean less than 1000 hic.
