A random sample of six steel beams has mean compressive strength of 58.392 psi (pounds per square inch) with a standard deviation of s = 648 psi. Test the null hypothesis H, = u = 58,000 psi against the alternative hypothesis H; H> 58,000 psi at 5% level of significance (value for I at 5 degree of freedom and 5% significance level is 2.0157). Here I denotes the population mean (A.MIE, Summer 2000)
Use the result of Exercise 45 to show that, if n independent random variables Xi have normal distribu-tions with the means μi and the standard deviations σi, then Y = a1X1 + a2X2 +···+ anXn has a normal dis-tribution. What are the mean and the variance of this distribution?
A manufacturer has developed a new fishing line, which he claims has a mean breaking strength of 15 kilograms with a standard deviation of 0.5 kilogram. To test the hypothesis that μ=15μ=15 kilograms against the alternative that p<15p<15 kilograms, a random sample of 50 lines will be tested. The critical region is defined to be x<14.9x<14.9(a) Find the probability of committing a type 1 error when H0H0 is true(b) Evaluate ββ for the alternatives p−14.8p−14.8 and μ=μ= 14.9 kilograms.
Nine determinations of the specific heat of iron had a standard deviation of 0.0086. Assuming that these deter-minations constitute a random sample from a normal population, test the null hypothesis σ = 0.0100 againstthe alternative hypothesis σ < 0.0100 at the 0.05 level ofsignificance.
It is desired to test the claim that a steady diet of wolfbane will cause a lycanthrope (werewolf) to lose 10 lbs. over 5 months. A random sample of 56 lycanthropes was taken yielding an average weight loss over 5 months of 12.5 pounds, with S = 7 lbs. Identify the critical value suitable for conducting a two-tail test of the hypothesis at the 5% level.
