Based on historical data from the past 5 years, 40 days were randomly chosen and their wind speed measurements were written down. This resulted in an average wind speed of 16 mph with a standard error of 0.6166 mph. A histogram of these wind speeds yielded a right-skewed shape. (a) Are the conditions met for constructing a confidence interval? (Check all that apply.) None of the conditions are met. The days were randomly chosen. It is reasonable to assume that weather conditions on the various days were independent of each other. The Nearly Normal condition is met. (b) Find the 95% confidence interval for the true average wind speed. (use 4 decimal places) (c) Does the above confidence interval provide evidence that a wind turbine would be cost effective? Yes, since the lower boundary is less than the required wind speed of 15 mph, it is possible the true average wind speed is less than 15 mph. No, since the lower boundary is greater than the required wind speed of 15 mph, there is evidence the true average wind speed is greater than 15 mph. No, since the lower boundary is less than the required wind speed of 15 mph, it is possible the true average wind speed is less than 15 mph. O Yes, since the lower boundary is greater than the required wind speed of 15 mph, there is evidence the true average wind speed is greater than 15 mph.
