Samples of size n = 1500 are randomly selected from the population of numbers (0 through 9)
produced by a random-number generator, and the proportion of even numbers is found for each
sample. What is the distribution of the sample proportions?
Solution
since 5 or more represents 50% of the numbers. the mean of the sample should be
50%. but by chance this can be higher or lower, and this chance would be normally distributed.
if the numbers sampling is, say 8 or more instead of 5 or more, then the distribution would be
skewed..
