a)Determine the mean of sample means distribution b) Determine the standard deviation (standard error) of sample means distribution c) Draw a Normal (bell-shaped) graph for sample means distribution by hand on a paper showing x and y axes without any values marked on them. However, label the values of mean and standard deviation as described below. The adult male heights in a country vary normally with mean of 70 inches and standard deviation of 4 inches. We draw many samples of size 100 from the above population using repeated random sampling and record the mean height for each sample to constitute a sample means distribution (?̅ -distribution). Do the above for the distribution.
