The correct interpretation of the standard deviation of the given discrete distribution is:
The mean number of days a member worked out would typically be about 1.6764 from the expected number of days.
<h3>What are the mean and the standard deviation of a discrete distribution?</h3>
- The mean of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
- The standard deviation is the square root of the sum of the difference squared between each outcome and the mean, multiplied by it's respective probabilities.
Hence:
E(X) = 0.4(0) + 0.12(1) + 0.13(2) + 0.15(3) + 0.06(4) + 0.02(5) + 0.02(6) + 0.01(7) = 1.36
Hence the correct option is:
The mean number of days a member worked out would typically be about 1.6764 from the expected number of days.
