While sometimes considered a pest since they can wreck wooden docks and piers, they are now being studied to determine whether the enzyme they secrete will allow us to turn inedible wood and plant waste into biofuel. A sample of 50 gribbles finds and average length of 3.1 mm with a standard deviation of 0.72. ments Use the following calculator to help you with the problem: Confidence Interval for a Mean Calculator eams a. Find the 95% confidence interval and the margin of error for the sample given. [hint: margin of error is the range of the interval divided by 2 i.e. How spread out the data is from the mean] sources b. Interpret the 95% confidence interval in context c. How would changing the sample size of the gribbles from 50 to 500 (same mean and standard deviation) affect the margin of error. Support your reasoning mathematically.
