show full solution Data on pull-off force (in pounds) for connectors used in an automobile engine application are as follows: 79.3, 75.1, 78.2, 74.1, 73.9, 75.0, 77.6, 77.3, 73.8, 74.6, 75.5, 74.0, 74.7, 75.9, 72.9, 73.8, 74.2, 78.1, 75.4, 76.3, 75.3, 76.2, 74.9, 78.0, 75.1, 76.8. a. Calculate the standard error of the point estimate(sample mean is 75.62). Provide an interpretation of the standard error. b. Calculate a point estimate of the proportion of all connectors in the population whose pull-off force is less than 73 pounds.
