Confidence interval of the population mean is given by: X+2 x where X is the mean, s is the standard deviation and n is the sample size. Create a function called "summary" that lists mean, %15 trimmed mean and the 95% bounds of confidence interval for a random sample. Use the function to calculate the statistics for the given sample where x= (1200, NA, 1205, 1203, 1296,1304) 1. 2.
Assume that population mean is to be estimated from the sample described. Use the sample results to approximate the margin of error and 95% confidence interval. n = 36, x = 64.4 seconds, s = 6.5 seconds. The margin of error is seconds. (Round to one decimal place as needed.) an example 4
