In a Manufacturing Facility Producing Fasteners, a Foreman Suspects That

question 103

Multiple Choice

In a manufacturing facility producing fasteners, a foreman suspects that the diameter of the bolts produced by his first-shift workers is greater than the diameter of the bolts produced by his second-shift workers. He takes a sample of five bolts from the first shift and a sample of four bolts from the second shift and measures the diameters in inches. Below are the results from five first-shift and four second-shift observations. The bolt diameter measurements are not normally distributed. At α = .05, can we conclude that his suspicion is correct?

• A) Reject the null hypothesis, the diameter is greater for first shift versus second shift.
• B) Do not reject the null hypothesis; there is no evidence that the diameters differ by shift.
