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.

80 minus 58 times 90 times 35 times 12455680

Bond [772]

According to the rules of math: multiplying comes before substraction(minus) so first multiply...

90×35×12455680= 39235392000

then minus 80 from the answer you got from multiplying.
39235392000-80= 39235391920
