Freshcrim specializes in the sales of ice cream from street trolleys in the centers of many cities. Some factors that may determine the sales of ice cream are: the atmospheric temperature, the location of the trolley, the rain and the humidity. However, there exists a hypothesis that the sales of ice cream during the summer are significantly correlated only with atmospheric temperature. They defined two variables: : the mean atmospheric temperature and : the sales. They considered the month of July of this year in a random sample of 33 cities. For each city in the sample, let  be the mean temperature in degrees Fahrenheit and  the mean sales per day in dollars per 100,000 residents. The data are given below. A regression model was run, with  as the dependent variable and  as the independent variable.   City       City       City     1 80.0 35.07   12 93.0 46.64   23 75.1 29.48 2 78.4 30.66   13 85.2 50.04   24 87.8 35.20 3 92.8 33.62   14 90.0 37.34   25 83.0 32.62 4 73.2 41.61   15 84.0 41.20   26 71.3 34.84 5 99.2 46.73   16 97.4 37.40   27 96.6 51.11 6 94.4 39.79   17 73.8 45.57   28 77.0 47.54 7 90.6 49.81   18 82.0 36.45   29 74.5 27.53 8 91.0 40.36   19 81.0 30.25   30 95.0 49.01 9 91.5 43.83   20 86.0 34.22   31 72.6 31.02 10 92.0 34.26   21 85.0 46.63   32 88.0 50.91 11 98.3 38.47   22 80.3 43.55   33 81.5 47.24   Question 1 Find the estimated regression equation for this sample.

Duke Energy reported that the cost of electricity for an efficient home in a particular neighborhood of Cincinnati, Ohio, was $104 per month. A researcher believes that the cost of electricity for a comparable neighborhood in Chicago, Illinois, is higher. A sample of homes in this Chicago neighborhood will be taken and the sample mean monthly cost of electricity will be used to test the following null and alternative hypotheses. Assume the sample data lead to rejection of the null hypothesis. What would be your conclusion about the cost of electricity in the Chicago neighborhood? What is the Type I error in this situation? What are the consequences of making this error? What is the Type II error in this situation? What are the consequences of making this error?
