Explanation of Solution
Given:
The proportion of silver candy wrappers during Holiday I = 30%
The proportion of silver candy wrappers during Holiday II = 50%
Sample size ( n ) = 40
Formula used:
The formulas are:
The formula to compute the mean and variance using binomial distribution are:
Calculation:
The mean and variance of silver candy wrappers during Holiday I can be calculated as:
The mean and variance of silver candy wrappers during Holiday II can be calculated as:
Thus, the mean and standard deviation are:
Thus, the required values are 32 and 4.29 respectively.
Hence, the correct option is (c).
