A new sample of captive African Gray Parrots is collected from the university's aviary. The sample is composed of 64 birds, with a mean memory score of 20 and a standard deviation of 5.0. Using this new data, what is the point estimate of u for figure memory among all African Gray Parrots? What is the 99% confidence interval for the true mean for figure memory in the parrots? What is the 99% margin of error? Show the formula for the single sample test (make sure you specify the test statistics you would use.)
