The average daily volume of a computer stock in 2011 was pe= 35.1 milion shares, according to a reliable source. A stock analyst believes that the stock volume in 2018 in different from the 2011 level. Based on a random sample of 30 trading days in 2018, he finds the sample mean to be 29.7 million shares, with a standard deviation of 133 million shares. Test the hypotheses by constructing a 95% confidence interval. Complete parto (a) through (e) bolow. GIRE (a) State the hypotheses for the test. Ho: P - 35.1 million shares H: 35.1 million shares (b) Construct a 95% confidence interval about the sample mean of stocks traded in 2018 With 95% confidence, the mean stock volume in 2018 is between million shares and milion shares (Round to three decimal places as needed.)

A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, X, is found to be 105, and the sample standard deviation, s, is found to be 10. (a) Construct a 96% confidence interval about if the sample size, n, is 13. (b) Construct a 96% confidence interval about if the sample size, n, is 27 (c) Construct a 98% confidence interval about if the sample size, n, is 13 (d) Could we have computed the confidence intervals in parts (a)-c) if the population had not been normally distributed?
