1. Suppose you are interested in estimating the mean egg length (in mm.) for the New Zealand bird population. The following link will direct you to an Excel table containing all the information collected from a simple random sample of 132 New Zealand birds: New Zealand birds.xlsx a) Find the mean and the standard deviation of the egg lengths measured in this sample. YOU HAVE TO DETERMINE THESE MEASURES USING THE EXCEL COMMANDS SHOWN IN CLASS. THE ANSWER TO THIS QUESTION MUST BE SUBMITTED IN EXCEL. ANSWERS FOR THIS QUESTION IN ANOTHER FORMAT WILL NOT BE CONSIDERED. b) Determine the best point estimate of the mean of egg lengths from all New Zealand birds. c) In a previous study, it was found that the standard deviation of the lengths of eggs from all new Zealand birds was 41.2 mm. Construct a 99% confidence interval for the mean egg length of birds found in New Zealand. YOU HAVE TO DETERMINE THE C.1. USING THE EXCEL COMMANDS SHOWN IN CLASS. THE ANSWER TO THIS QUESTION MUST BE SUBMITTED IN EXCEL. ANSWERS FOR THIS QUESTION IN ANOTHER FORMAT WILL NOT BE CONSIDERED. d) If we find an egg from a New Zealand bird, and the length of the egg is 79 mm, how this length compare with the average egg length of birds from New Zealand? BASE YOUR CONCLUSION ON THE C.V. OBTAINED. EXPLAIN VERY WELL YOUR ANSWER
