In a sample of 138 tables, the average height was found to be 32.6in. with a variance of 2.8. Give a point estimate for the popu

vesna_86 [32]

Answer:

$\hat{\sigma}^2 = 2.8$

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 138

Average = 32.6 inch

Population variance,

$\sigma^2 = 2.8$

We have to find a point estimate for the population variance of the height.

The point estimate for the population variance is the population variance itself.

$\hat{\sigma}^2 = \sigma^2 = 2.8$

Thus, the point estimate of population variance is the population variance that is 2.8.

Answer:

It would be the last choice. Base= 8 in; height= 3 in

Step-by-step explanation:

It gives you the measurement for the height you just have to read what the ruler says at the bottom. When does the shape stop on the ruler? That number would be the answer in this case it would be the last choice.
