3. Write a function to compute the mean and SD of height using only the first N entries, and then a. Plot these mean and standard values for N ranging between 3 and 500. b. Looking at these plots, what value of N would you choose to provide a good measure of mean height, and likewise for a good measure of the SD of height? c. Determine the minimum value of N such that the resulting mean is within 0.5% of the mean computed in Q2 (i.e., using all data) d. Determine the minimum value of N such that the resulting SD is within 0.5% of the SD computed in Q2 (i.e., using all data) e. Given results of parts c and d, does your answer to part b change? Explain and briefly discuss
