Answer #1

speed limit = 65 miles / hour

                            1 mile = 1.60934 km

                              1 hour = 3600 sec

               65 miles/ hour = 65 * 1.60934 / 3600 = 0.029 km/ sec

    The speed limit on the freeway is 65 mph. The chief of the police department has their radar guns tested: from repeated measurements, the errors in the readings seem to follow a normal distribution. Using the data and assuming the radar guns provide unbiased measurements of the true speeds, the chief issues a policy that officers should not stop cars unless the reading is at least 71 mph. She says this policy ensures that no more than 2.5% of cars...
