The data Highway Speeds, in the accompanying workbook, show the speeds of 40 cars on a Satu rdav afternoon 8) bi C) The speed limit on this portion of Interstate 95 is 65 mph. Using the mathematical svmbols, give the hypotheses used to decide if the average speed of all cars that afternoon is greater than the speed limit. HO: HA: Calculate the value of the test statistic and the p-value. Sh ow how these could be calculated \"by hand\" from appropriate formulas. i) Test statistic ii) p- value [either an exact value or a \"bracketed\" value) If he or she uses 0. = .01, does the officer have signicant evidence that the average speed is over the limit?
