Statistics

Question: Biology and Environmental Science A special water channel is being constructed, connected to the Campbell River in British Columbia, to provide more area for chinook salmon spawning. The plans call for the channel to be 23 meters wide. Following completion, a random sample of 18 locations along the channel was selected, and the width at each location was measured. The sample mean was x¯ = 24.6 meters. Assume the distribution of channel widths is normal and σ = 2.28 meters.

a. Is there any evidence to suggest the mean width of the channel is greater than 23 meters? Use a = 0.01.

b. Find the p value associated with this hypothesis test.
