Suppose that 20% of the candies are yellow.If you collected random samples
of only 20 yellow candies and made 100 groups of these samples, plot the
expected distribution of the results as the number of yellow candies versus
the frequency of that particular outcome.
Is this distribution "normal"?
不明白 If you collected random samples of only 20 yellow candies and made
100 groups of these samples,什么意思？有大牛能给指点指点不，谢谢了。 |
