Do data supply sufficient evidence to allow manufacturing

Reference no: EM13210236

A major car manufacturer wants to test a new engine to determine whether it meets new air pollution standards. The mean emission of all engine of this type must be less than 20 parts per million of carbon. Ten engines are manufactured for testing purposes, and the emission level of each is determined. The data reveal that the mean is 17.57 and the standard deviation is 2.9522. Do the data supply sufficient evidence to allow the manufacturer to conclude that this type of engine meets the pollution standards? Assume that the manufacturer is willing to risk a Type I error with probability 0.01.
