Exercise 5-45 Algo A car manufacturer is trying to develop a new sports car. Engineers are hoping that the average amount of time that the car takes to go from 0 to 60 miles per hour is below 6 seconds. The manufacturer tested 14 of the cars and clocked their performance times. Three of the cars clocked in at 5.8 seconds, 3 cars at 5.9 seconds, 5 cars at 6.0 seconds, and 3 cars at 6.1 seconds. At the 5% level of significance, test if the new sports car is meeting its goal to go from 0 to 60 miles per hour in less than 6 seconds. Assume a normal distribution for the analysis. (You may find it useful to reference the t table.) a. Specify the competing hypotheses to test this belief. Ho: u = 6; HA: u 7 6 Ho: u = 6; HA: u < 6 Ho: u s 6; HA: u > 6 b. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round final answer to 3 decimal places.) Test statistic
