In a sample of 66 cabinets, the average height was found to be 36.5in. with a variance of 1.7. give a point estimate for the population standard deviation of the height of the cabinets. round your answer to two decimal places, if necessary.

1.30 in.

Step-by-step explanation:

Let x denotes the height of cabinets.

We are given that ,

In a sample of 66 cabinets, the average height was found to be 36.5 in. with a variance of 1.7.

i.e. sample mean =

Sample variance =.

Since standard deviation is the square root of variance.

i.e. Sample standard deviation :

Since the sample standard deviation(s) is the best point-estimate of the population standard deviation .

Then,  a point estimate for the population standard deviation of the height of the cabinets.= 1.30 in.
