An engineer suspects that a power plant in the city is increasing the air pollution in the vicinity of the plant. A sample of measurements of carbon monoxide (in mg/m3 of air) in the vicinity of the plant (Group 1) is obtained for comparison with another sample obtained from other locations (Group 2) in the city. Dataset is available at pollution.txt Assume that the measurements for both groups follow a normal distribution and the populations' variances are equal. By the 95% confidence interval for the difference between the means of the first group and the second group. i.e., ₁-2, we can conclude that A: With 95% confidence, we have evidence to indicate that there is a difference between the amount of carbon monoxide in the vicinity of the plant and other places. B: With 95% confidence, we have NO evidence to indicate that there is a difference between the amount of carbon monoxide in the vicinity of the plant and other places. OA OB

In 1998, as an advertising campaign, the Nabisco Company announced a "1000 Chips Challenge," claiming that every 18-ounce bag of their Chips Ahoy cookies contained at least 1000 chocolate chips. Dedicated statistics students at the Air Force Academy (no kidding) purchased some randomly selected bags of cookies and counted the chocolate chips. Some of their data are given below.1219 1214 1087 1200 1419 1121 1325 1345 1244 1258 1356 1132 1191 1270 1295 1135Find a 95% confidence interval for the mean number of chips in a bag of Chips Ahoy Cookies.
