5. Suppose you are hired by O-DOT to conduct a study on the average speed of commuters on a certain section ten of I-5. The speed limit is 60mph. a.) Use the following data (which come from a normally distributed population) to construct a 95% confidence interval for the true average commuter speed. Please use proper notation when reporting the confidence interval, and make a concluding statement IN THE CONTEXT of the question. 62 61 57 61 54 61 59 58 59 69 60 67 sonsbitnoo bibl Log b.) Now suppose that O-DOT is unhappy with the margin of error you found in your results, and would like a margin of error of 1.5 miles per hour. First, EXPLAIN what you would have to do and then make the proper calculations to support your explanation.
