The standard deviation of the water depth is .
Further Explanation:
The standard deviation is a measure of deviation of data values from mean. And it also measure the spreadness of the data values.
More the standard deviation more the spreadness and less the standard deviation less will be the spreadness.
The random variable X follows uniform distribution in interval a to b.
The variance can be obtained as,
Calculation:
The standard deviation is square root of variance.
The depth of water is in between the data set to .
The depth of water follows uniform distribution.
The variance of the depth of water can be obtained as,
The standard deviation can be obtained as,
The standard deviation of the water depth is .
