a simple random sample of size n is drawn from a normally distributed population, and the mean of the sample is , while the
standard deviation is s. what is the 99% confidence interval for the population mean?

Using the given information, solve for x. what is the length of ab? what is the length of rs? a) x = 2; ab = 4; rs = 8 b) x = 6; ab = 8; rs = 16 c) x = 4; ab = 6; rs = 12 d) x = 8; ab = 10; rs = 20
