While traveling through South America, a student decides to analyze which country isthe friendliest. He measures friendliness by seeing whether or not a person, whenasked for directions, gives a reply. For each country, he gathers data on hundreds ofpeople. The four countries analyzed are Argentina, Chile, Brazil, and Uruguay. Please simply write the letter for the test as your answer. Here are the tests: A: onesample z-test B: one-sample t-test C: t-test for the difference between means fortwo related samples D: t-test for the difference between means for two independentsamples with homogeneity of variance E: t-test for the difference between means fortwo independent samples with heterogeneity of variance F: a one sample z-test forproportions (or a chi-square goodness of fit) G: chi-square goodness of fit only(where a one sample z-test of proportions isn't appropriate) H: a two-sample z-testfor the difference between proportions (or a chi-square test of independence) I: chi-square test of independence only (where a two-sample z-test for the differencebetween proportions isn't appropriate.)

Several years ago, two companies merged. One of the concerns after the merger was the increasing burden of retirement expenditures. An effort was made to encourage employees to participate in the 401(k) accounts. Nationwide, 62% of eligible workers participated in these accounts. The accompanying data table contains responses of 30 employees of the company when asked if they were currently participating in a 401(k) account. Complete parts a through d. Click the icon to view the data table. a. Determine the sample proportion of company workers who participate in 401(k) accounts. The sample proportion is (Round to three decimal places as needed.) b. Determine the sampling error if in reality the company workers have the same proportion of participants in 401(k) accounts as does the rest of the nation. The error is. (Round to three decimal places as needed.) c. Determine the probability that a sample proportion at least as large as that obtained in the sample would be obtained if the…
A researcher wanted to know whether the level of frustration over high gas prices differed for different types of vehicle owners. Following a sharp increase in the price of gas, the researcher asked 30 people to indicate their level of frustration with prices at the pump (frustration scores ranged from 1 to 10, with higher scores indicating greater frustration). Ten people were surveyed who owned a motorcycle as their primary means of transportation (coded a 1 in the data file 1), 10 were surveyed who owned a hybrid vehicle (coded a 2 in the data file 1), and 10 were surveyed who owned a non-hybrid vehicle (coded a 3 in the data file Exam 3). a.State the null and alternative hypotheses. b. State a research question for the data.

Is fishing better from a boat or from the shore? Pyramid Lake is located on the Paiute Indian Nation in Nevada. President, movie stars, and people who just want to catch fish go to Pyramid Lake for really large cutthroat trout. Let row B represent hours per fish caught fishing from the shore and let row A represent hours per fish caught using a boat. The following data re paired by month from October through April. Oct.

B: Shore 1.6 1.8 2.0 3.2 3.9 3.6 3.3 A: Boat 1.5 1.4 1.6 2.2 3.3 3.0 3.8 Use a 1% level of significance to test if there is a difference in the population mean hours per fish caught using a boat compared with fishing from the shore.
Students at a number of universities were asked if they agreed that their education was worth the cost. One variable in the table is the percentage of students at the university who responded strongly agree.

A study investigated whether price affects people's judgment. Twenty people each tasted six cabernet sauvignon wines and rated how they liked them on a scale of 1 to 6. Prior to tasting each wine, participants were told the price of the wine. Of the six wines tasted, two were actually the same wine, but for one tasting the participant was told that the wine cost $10 per bottle and for the other tasting the participant was told that the wine cost $90 per bottle. The participants were randomly assigned either to taste the $90 wine first and the $10 wine second, or the $10 wine first and the $90 wine second. Differences were calculated by subtracting the rating for the tasting in which the participant thought the wine cost $10 from the rating for the tasting in which the participant thought the wine cost $90.
