The mean of the sampling distribution is the same as the probability of correctly identifying a Skittle's color, which is 17%. So, the mean here is 0.17. To find the standard deviation (which tells us how much the results might vary), we use a formula that takes in...

[解析]According to Chebyshev’s Inequality, for any distribution, the minimum percentage of observations that lie within kstandard deviations of the distribution mean is equal to: 1-(1/k2), with k equal to the number of standard deviations. If k= 2, then the percentage of distributions is ...
