Socially conscious investors screen out stocks of alcohol and tobacco makers, firms with poor environmental records, and companies with poor labor practices. Some examples of "good," socially conscious companies are Johnson and Johnson, Dell Computers, Bank of America, and Home Depot. The question is, are such stocks overpriced? One measure of value is the P/E, or price-to-earnings ratio. High P/E ratios may indicate a stock is overpriced. For the S&P Stock Index of all major stocks, the mean P/E ratio is u = 19.4. A random sample of 36 "socially conscious" stocks gave a P/E ratio sample mean of x = 18.0, with sample standard deviation s = 4.2. Does this indicate that the mean P/E ratio of all socially conscious stocks is different (either way) from the mean P/E ratio of the S&P Stock Index? Use a = 0.01. (a) What is the level of significance? State the null and alternate hypotheses. O Họ: u + 19.4; H1: µ = 19.4 Ο Hg: μ >19.4 ; H: μ= 19.4 O Họ: u = 19.4; H1: µ > 19.4 Ο Hρ: μ 19.4; Η: μ+ 19.4 Ο H0: μ= 19.4; H: μ < 19.4 (b) What sampling distribution will you use? Explain the rationale for your choice of sampling distribution. O The Student's t, since the sample size is large and o is known. O The Student's t, since the sample size is large and o is unknown. O The standard normal, since the sample size is large and o is known. O The standard normal, since the sample size is large and o is unknown. What is the value of the sample test statistic? (Round your answer to three decimal places.) (c) Find the P-value. (Round your answer to four decimal places.)

In order to determine a realistic price for a new product that a company wants to market the company’s research department selected 10 sites thought to have essentially identical sales potential and offered the product in each at a different price. The resulting sales are recorded in the accompanying table:    Price ($) Sales ($1,000s) 15.00 15 15.50 14 16.00 16 16.50 9 17.00 12 17.50 10 18.00 8 18.50 9 19.00 6 19.50 5  a). Explain carefully, which of the variables above is the independent variable and which is the dependent variable.
