The average gasoline price of one of the major oil companies has been hovering around $2.20 per gallon. Because of cost reduction measures, it is announced that there will be a significant reduction in the average price over the next month. In order to test this belief, we wait one month, then randomly select a sample of 36 of the company's gas stations. We find that the average price for the stations in the sample was $2.15. The standard deviation of the prices for the selected gas stations is $.10. Given that the test statistic for this sample is t = –3, determine the p-value.

Consider this scenario: The population of a city increased steadily over a ten-year span. The following ordered pairs show the population x and the year y over the ten-year span in the form(x, y)for specific recorded years. Use linear regression to determine a function y, where the year depends on the population. Round to three decimal places of accuracy.(2500, 2001), (2650, 2002), (3000, 2004), (3500, 2007), (4200, 2011)Predict when the population will hit 14,000.The linear regression model based on this data predicts that this will happen during the year. So, y= ___ .
