The accompanying table gives results from a study of words spoken in a day by men and women. Assume that both samples are independent simple random samples from populations having normal distributions. Use a 0.05 significance level to test the claim that the numbers of words spoken in a day by men vary more than the numbers of words spoken in a day by women. n x s Men 187 15,668.9 8,632.2 Women 211 16,215.4 7,301.4 => Identify the test statistic. (Round to two decimal places as needed.) Use technology to identify the P-value. (Round to three decimal places as needed.) What is the conclusion for this hypothesis test? reject/fail to reject?
Incorrect. The weight of boxes of candy is a normal random variable with mean and variance 1/10 pound2. The prior distribution for u is normal with mean 5.01 pound, and variance 1/25 pound2. A random sample of 9 boxes gives a sample mean of x = 5.02 pound. Find the Bayes estimate of u. Round your answer to three decimal places. ji i 5.015
