Data on pull-off force (pounds) for connectors used in an automobile engine application are as follows:
79.4 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 72.3 73.8 74.2 78.1 75.4 76.3 75.3 76.2 74.9 78.0 75.1 76.8
(a) Calculate a point estimate of the mean pull-off force of all connectors in the population.
(b) Calculate a point estimate of the pull-off force value that separates the weakest 50% of the connectors in the population from the strongest 50%.
(c) Calculate the point estimate of the population variance.
(d) Calculate the point estimate of the population standard deviation.
(e) Calculate the standard error of the point estimate found in part (a).
(f) Calculate a point estimate of the proportion of all connectors in the population whose pull-off force is less than 73 pounds.
