A auto maker is interested in information about how long transmissions last. A sample of transmissions are run constantly and the number of miles before the transmission fails is recorded. The auto maker claims that the transmissions can run constantly for over miles before failure. The results of the sample are given below. Image loading...Image loading...What condition is met for the use of a -distribution?Degrees of freedom 0.018 2.17 The population is stated to be not skewed. 42 41 150 1.889 1 2 3 ✖ Each incorrect answer is highlighted. Expected: The sample size is larger than 30. Degrees of freedom On the computer output, the sample size is indicated by Observations, the degrees of freedom are indicated by df, is indicated by Mean, the -statistic is indicated by t Stat, and the -value is indicated by P(T<=t) one-tail. The standard deviation is the square root of the Variance. 1
