The monthly sales of cars (in L.L) in a show rooms for a company are assumed to follow a normal distribution. A sample of monthly sales has been observed, and given as (in Millions of L.L): 125 145 88 140 115 138 97 104 125 The confidence interval for the mean sales in all salesrooms, at a 99% level is: O (97.19, 142.15) O (96.63, 144.92) O (92.51, 159.05) O (87.37, 157.96)

The price to earnings ratio (P/E) Is an Important tool in financial work. A random sample of 14 large U.S. banks (JP Morgan Chase, Bank of America, and others) gave the following P/E ratios.t 24 16 22 14 12 13 17 22 15 19 23 13 11 18 The sample mean is x = 17.1. Generally speaking, a low P/E ratio indicates a "value" or bargain stock. Suppose a recent copy of a magazine indicated that the P/E ratio of a certain stock index is H = 18. Let x be a random variable representing the P/E ratio of all large U.S. bank stocks. We assume that x has a normal distribution and o = 4.7. Do these data indicate that the P/E ratio of all U.S. bank stocks is less than 18? Use a = 0.01. (a) What is the level of significance? State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or two-tailed test?
