Answer:

0.8333333333333333 (repeating)

Step-by-step explanation:

Well first the point of this problem is to get "a" by it self so.

-2a = a - 10/4

remove the fraction by multiplying 4 on both sides.

-8a = 4a - 10

now move 4a over to the other side to isolate the 10.

-12a = -10

now divide to get a by it self

-10/-12 = 0.8333333 (repeating)

**Remember a negative divided by a negative is a positive.

b. CHISQ.TEST

Step-by-step explanation:

Notation and previous concepts

A chi-square test is "used to test if the variance of a population is equal to a specified value. This test can be either a two-sided test or a one-sided test. The two-sided version tests against the alternative that the true variance is either less than or greater than the specified value"

The statistic is given by:

$\chi^2 = \sum_{i=1}^n \frac{(O_i-E_i)^2}{E_i}$

In order to calculate the p value we need to have in count the degrees of freedom , on this case $df=(rows-1)(#cols-1)$ . And we can calculate the p value would be given by:
