(4] Imagine that we take a sample from a population of interest. Sample data For the following questions use the sample values to the right: 21 20 13 13 Assume that this sample accurately reflects the mean and standard 15 20 deviation of the population so you can use the normal distribution and 19 22 2 scores for the problems below. (If you've read ahead in your book or lab manual you know we should really uset scores, don't worry about this right now. use the 2 scores) (a) Assuming that the population data is normally distributed. what is the value Val. = 19.51 that you expect 67% ot the data in the population to be smaller than? (round to nearest 0.01)
