A new design for the braking system on a certain type of car has been proposed. For the current system, the true average braking distance at 40 mph under specified conditions is known to be 120 ft. It is proposed that the new design be implemented only if sample data strongly indicates a reduction in true average braking distance for the new design. Define the parameter of interest and state the relevant hypotheses. Suppose braking distance for the new system is normally distributed with o = 10. Let X denote the sample average braking distance for a random sample of 36 observations. Assume the rejection region is = 115, calculate the probability of a. b. %3D

A chemical engineer ending his shift at the factory noticed that the time is between 3 and 4 o’clock. Fifteen minutes later, he noticed that the minute hand of the clock was already ahead of the hour, a deviation from the previous position when he ended his shift where the minute was behind the hour hand. What is the exact time when he ended his shift?a. 3 : 16 : 00.0b. 3 : 08 : 51.6c. 3 : 19 : 03.1d. 3 :17 : 42.3e. None of these
