In a sample of 138 tables, the average height was found to be 34.3in. with a variance of 0.7. Give a point estimate for the population variance of the height of the tables. Round your answer to two decimal places, if necessary.

0.70.

Step-by-step explanation:

Given : For the sample of  138 tables, the average height was found to be 34.3in. with a variance of 0.7.

It means the sample variance  () is 0.70.

Since , we know that the sample variance is the best point estimate of the population variance in a statistical study.

Therefore ,  a point estimate for the population variance of the height of the tables would be 0.70.

Hence, the correct answer is 0.70.
