Data on pull-off force (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.
i. Calculate a point estimate of the mean pull-off force of all connectors in the
population. State which estimator you used and why.
ii. 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%.
iii. Calculate point estimates of the population variance and the population standard
deviation.
iv. Calculate the standard error of the point estimate found in part (a). Provide an
interpretation of the standard erro
