Question 1 (5 points) Sigma known, p-value approach The State of Arizona is deciding whether or not to allocate $200M to add an additional lane to the Tucson-Phoenix I-10 freeway. They have decided that a lane will be added if the average driving time between the two cities exceeds 2 hours. A randomly selected sample of 100 cars, based on stratified sampling method (grouped by day of week), found a sample average driving time of 2.17 hours. If we can assume the population is normal with a population standard deviation of 1.1, will a new lane be added? Use a Type 1 Error of 5%. a) No, since the p-value of 0.06 is greater than the type 1 error allowed of 0.05 ( b) Yes, since the p-value of 0.06 is greater than the type 1 error allowed of 0.05 O c) No, since the p-value of 0.044 is less than the type 1 error allowed of 0.05 O d) Yes, since the p-value of 0.044 is less than the type 1 error allowed of 0.05 Previous Page Next Page
