The confidence interval of the height is
Further Explanation:
Given:
The mean height is
The standard deviation is
Explanation:
The empirical rule is used to check that the given data set is normally distributed.
Empirical rule is defined as follows,
Approximately data points will lie within the first standard deviation of the mean.
Approximately data points will lie within the two standard deviation of the mean.
Approximately data points will lie within the three standard deviation of the mean.
Here, represents the mean and represents the standard deviation.
confidence interval of the mean can be obtained by subtracting or adding one times the standard deviation from the mean,
The confidence interval of the height is
