1. (15 points} A reporter 'om MTL Blog bought 9 roast chickens 'om Rotisserie Romados. Each chicken was weighed and yielded the following data (pounds): 5.2, 5.3, 5.5, 5.5, 15, 5.1, 5.5, 5.5, 5.9 a) Assuming that the nine roast chickens were randomly sampled and that the weight of a chicken is uonuall}; distributed, estimate the true average weight p: and standard deviation of the weight or using maximum likelihood estimation {MILE}. Please show the procedure for deriving the expressions of the estimates, and then plug in the weights for the numerical results. Round your results to two decimal places. h} Again assuming a normal distribution, estimate the weight below which 8% of all roast chickens will have their weights. [I-Ijnt: what is the El percentile in terms of p and 0?]
