    Let x be a random variable that represents the pH of arterial plasma (i.e., acidity of the blood). For healthy adults, the mean of the x distribution is μ = 7.4.† A new drug for arthritis has been developed. However, it is thought that this drug may change blood pH. A random sample of 41 patients with arthritis took the drug for 3 months. Blood tests showed that x = 8.5 with sample standard deviation s = 3.4. Use a...

    Let x be a random variable that represents the pH of arterial plasma (i.e., acidity of the blood). For healthy adults, the mean of the x distribution is μ = 7.4.† A new drug for arthritis has been developed. However, it is thought that this drug may change blood pH.

    A sample of size n = 19 has variance s2 = 1.96. At α2 = .05 in a right-tailed test, does this sample contradict the hypothesis that σ2 = 1.21? (a) Choose the correct null and alternative hypotheses. H0: σ2 ≥ 1.21 vs. H1: σ2 < 1.21 H0: σ2 = 1.21 vs. H1: σ2 ≠ 1.21 H0: σ2 ≤ 1.21 vs. H1: σ2 > 1.21. (b) Calculate the decision rule.

    Let x be a random variable that represents red blood cell count (RBC) in millions of cells per cubic millimeter of whole blood. Then x has a distribution that is approximately normal. For the population of healthy female adults, suppose the mean of the x distribution is about 4.66. Suppose that a female patient has taken six laboratory blood tests over the past several months and that the RBC count data sent to the patient's doctor are as follows. 4.9...

    1. The mean of a sample of 25 measurements of the diameter of a camshafts on a production line was 6.7 cm. Manufacturer specifications call for a mean diameter of 7 cm. Assume the diameters are known to have a normal distribution with unknown mean, μ, and known variance, σ2 = .2 (cm)2. a. Test H0: μ = 7 versus Ha: μ < 7 at level of significance α =.01. Find the p-value and state whether to reject the null...

    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...
