Question:
A local company installs natural-gas barbecues. As part of the installation, a ditch is dug to lay a small natural-gas line from the barbecue to the main line. On average, the depth of these lines seems to run about 30 cm. The company claims that the depth does not vary by more than 103.2 cm2 (the variance). To test this claim, an analyst randomly took 22 depth measurements at different locations. The sample average depth was 34 cm with a standard deviation of 15.2 cm. Is this enough evidence to reject the company’s claim about the variance? Assume line depths are normally distributed. Let α = 0.05.
