Use this equation to answer the following;A) How many murders per 100,000 residents can be expected in a state with 2.7 thousand automatic weapons?Answer = _________ Round to 3 decimal places.B) How many murders per 100,000 residents can be expected in a state with 4.1 thousand automatic weapons?Answer = ___________ Round to 3 decimal places.Problem 3 The fuel economy of two small cars is being studied by driving 15 of each in different conditions and recording the fuel consumed. The resulting fuel economies, in litres/100 km, are as follows; Car A: 5.0 5.4 5.2 4.7 6.1 5.6 5.1 5.1 4.8 5.6 5.3 4.3 5.8 5.2 4.8 Car B: 5.7 6.1 4.7 5.2 5.3 5.7 5.6 5.3 6.7 5.8 6.2 5.6 5.6 6.2 5.7 For each car, compute, by hand, a) the sample mean, b) the sample standard deviation, and c) the sample median of the fuel economy. d) Use MINITAB to produce parallel boxplots. e) Based on the results in a)-d), which car do you think performs better? Why? (Here, you will only be expected to give your best opinion. Later, we will investigate more formal approaches to answering this question.)

The concentration of mercury in fish tissue can be obtained by catching fish and sending samples to a lab for analysis. A study was conducted on fish from the Waccamaw and Lumber Rivers to investigate mercury levels in tissues of largemouth bass. At several stations along each river a group of fish were caught, weighed and measured; in addition a filet from each fish was sent to a lab so that the tissue concentration of mercury could be determined. In all, 171 fish were caught at 15 different research stations along the Waccamaw and Lumber Rivers. Data from fish caught at one of these stations is shown in the following table: length weight 1616 47.0 1862 48.7 2855 55.7 1199 45.2 1320 44.7 1225 43.8 870 38.5 1455 45.8 1220 44.0 1033 40.4 Compute the correlation between length and weight for these fish.

In many communities, when people buy a house in the area, they receive a “Welcome Wagon” gift basket containing coupons to local restaurants. The idea of the marketing campaign is to include a free two month membership to the country club in the gift basket with the hope that once “new” residents try the country club then at least a certain proportion will want to become real members. One member of the Club’s Executive Council believes that at least 25% of the people who receive the coupons for the free membership will use the coupon. When testing the hypothesis that at least 25% of the people who receive the coupons for the free membership will use the coupon, what is the null and alternative hypothesis?
