8 0

Answer:

Step-by-step explanation:

Adding both equations

4x+5y+5y-4x=19+38

10y = 57

y= 5.7

Subtracting equation i from ii

5y-4x-4x-5y=38-19

-8x=9

x= -0.9

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.
