- The NAEP considers that a national average of 283 is an acceptable performance. Using α = .05, run a two-tail t-test for one sample to test Ho: µ=283 for the 2019 scores. Report the t-obt, df, and p-values. Would you reject the null hypothesis that the 2019 scores come from a population with average 283? If this is the case, does it come from a population from larger or smaller average?In a random sample of 320 cars driven at low altitude, 40 of them exceeded the standard 10 grams of particulate pollution per gallon of fuel consumed. In another independent random sample of 80 cars driven at high altitude, 20 of them exceeded the standard. Let P 1be the true proportion of cars that exceed the standard in low altitudes and P 2be the true proportion of cars that exceed the standard in high altitudes. What is the test statistic for testing this hypothesis.A nationwide study of undergraduate students reported that the mean number of drinks consumed per week during the spring semester is 7.96. The mean number of drinks consumed per week at USC is 7.64 (s.d.=2.55, N=412 Health services is concerned that USC students are consuming significantly more alcohol per week than the national average. Using an alpha level of .05, Is there sufficient evidence to be concerned? Be sure to select the correct critical value for the alternative hypothesis, and then use this evidence to make your conclusion
- A computer manufacturer believes that the proportion of hardware malfunctions is different in humid climates than in dry climates. To test this claim, the manufacturer takes a random sample of 400 machines sold in Florida (humid) and 400 machines sold in Arizona (dry). The manufacturer finds that 44 of the machines in Florida and 24 of the machines in Arizona had hardware malfunctions. a.Specify the competing hypotheses to test the manufacturer's claim. b.Calculate the value of the relevant test statistic. c.Compute the p-value. d. Does the evidence support the computer manufacturer's claim at the 10% significance level?A computer manufacturer believes that the proportion of hardware malfunctions is different in humid climates than in dry climates.

When the data results are analyzed, the researchers get a p-value of 0.07. What decision should the researchers make? A. We accept the null hypothesis that the drug is no better than a placebo. B. We cannot reject the null hypothesis that the drug is no better than a placebo. C. We accept the alternative hypothesis that the drug is no better than a placebo. D.

- A recent clinical trial compares the use of Drug A to the standard treatment of symptomatic genital herpes. The study involves 10, 000 people with genital herpes who are randomly assigned to receive Drug A or standard treatment. Results of the trial show that the duration of symptoms in patients who received Drug A is 4 days versus 4-5 days in patients who received standard symptomatic measures (p<0.5). The manufacturer of Drug A recommends the use of Drug A in the clinical treatment of genital herpes. Based on the study’s results, which of the following is the most appropriate reason to question the manufacturer’s recommendation? a) The investigators used an inappropriate study design b) It is likely that there was a Type I error c) It is likely that there was Type II error d) The observed difference is not clinically significant e) The observed difference is not statistically significant f) There was insufficient powerIn a completely randomized experimental design, three brands of paper towels were tested for their ability to absorb water.
