A random sample of 25 shoppers showed that they spend an average of $60.45 per visit at the Saturday Mornings Bookstore. The population standard deviation is $4.85. Assume the population is normally distributed. Find the 99% confidence interval for the average amount of money spent by shoppers at the store. Hypothesis Tests (18 points each) For each hypothesis test: Determine the null and alternative hypotheses. Identify the sample statistics. Specify the meaning of the population parameter being used in the hypotheses. In other words, define or p. Compute the standardized test statistic. Round to two decimal places. Determine the P-value. Round to three decimal places. Draw a sketch to show the P-value. Make a decision about the hypotheses and interpret the decision regarding the underlying
