Show on TI-84 and handwritten please and thank you  A sample of size 8 is drawn from a population with an unknown distribution, and the sample mean is calculated.  If the mean of the population is 27 with a standard deviation of 8.5, what is the probability the sample mean will be smaller than 20?   0.0099 0.2051 0.7949 0.9901 The probability cannot be determined using typical methods since the shape of the sampling distribution is unknown.
