A random sample of 120 people who shop for groceries exclusively at Harris Teeter found that 25% primarily use online ordering for their family's groceries. A random sample of 150 people who shop for groceries exclusively at Giant found that 36% primarily use online ordering for their family's groceries. Is this evidence that there is a difference between the two stores for the proportion of people who shop online for groceries? Use a significance level of alpha=0.05 for your inference procedure.
A trucking firm is considering the installation of a new, low-restriction engine air filter for its long-haul trucks, but doesn’t want to make the switch unless the new filter can be shown to improve the fuel economy of these vehicles. A test is set up in which each of 10 trucks makes the same run twice once with the old filtration system and once with the new version. Given the sample results shown below, use the 0.05 level of significance in determining whether the new filtration system could be superior. Truck Number Current Filter (mpg) New Filter (mpg) 1 7.6 7.3 2 4.1 7.2 3 10.4 6.8 4 6.9 10.6 5 5.6 8.8 6 7.9 8.7 7 5.4 5.7 8 5.7 8.7 9 5.5 8.9 10 5.3 7.1 Do reject or fail to reject H0?

A study of color in tiger beetles is conducted to support the contention that the proportion of black beetles may vary from locality to locality (alpha=0.05). A sample of 500 beetles caught in one season near Providence, Rhode Island, yielded 95 black beetles. A catch of 112 beetles from Aqueduct, New York, contained 17 black individuals. 1. What is null and alternative hypothesis? 2. What proportions did you observe in the two localities? 3. What is the null standard error for the difference? 4. Calculate the appropriate test statistic. 5. What p-value do you associate with that statistic? 6. What do you conclude about the proportion of black beetles in the two locations?

A simple random sample of 18 male students at a university has an average height of 70 inches. The average height of men in the general population is 69 inches. Assume that male height is approximately normally distributed with σ = 2.8 inches. Conduct a two-sided hypothesis test to determine whether the male students have heights that are significantly different than expected. Show all hypothesis testing steps.

An article from the American Journal of Public Health reports the results from a randomized study designed to evaluate the efficacy of an intervention targeted to Hispanic/Latino men who identify as gay, bi-sexual or other men who have sex with men (MSM). A representative sample of 254 such men was randomized to be in either the intervention group (n=152, with 141 ultimately participating in the study) or the control group (n=152, with 147 ulitmately participating in the study). The primary outcome under study getting tested for HIV within the six-months following group assignment (randomization) among those who had been sexually active in this same six-month follow-up period. At six months of follow-up, 141 subjects in the intervention group reported having had sex (with men and/or women) since randomization. Of these 141 men, 114 had been tested for HIV since being randomized. At six months of follow-up, 147 subjects in the control group reported having had sex (with men…
