Suppose that the body weights of Roborovski dwarf hamsters are normally distributed with a m of 22 g and a standard deviation of 1.2 g. A scientist thinks that conditions in the Ordos desert affecting the hamsters in the region, She collects a random sample of n=25 hamsters from the Or and finds the sample mean weight to be 21.4 g. Find the probability of observing a sample mean than or equal to 21.4 if the mean weights of the hamsters in the Ordos desert is 22g as reported..
