Sampling Error: 1. Elephants are the mammals with the longest gestation period (time of pregnancy)..
Sampling Error: 1. Elephants are the mammals with the longest gestation period (time of pregnancy). African elephants have a mean gestation period of 640 days and a standard deviation of 66 days. Assume that a random sample of 35 African elephants was taken, what is the probability that the sample mean gestation period is within 20 days of the population mean? (That is, the probability that the sampling error is less than 20 days.) Look back at your work and notice what the numerator of each of your z scores was. 2. Asian elephants have gestation periods with a standard deviation of 53 days. Assume that a random sample of 35 Asian elephants was taken, what is the probability that the sample mean gestation period is within 20 days of the population mean? (That is, the probability that the sampling error is less than 20 days.) Notice that we do not know what the population mean is. May 11 2022 01:56 AM
