Answer:

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:

p_v =P(\chi^2 >\chi^2_{calc})

But the correct comand is given by:

b. CHISQ.TEST(Actual range, Expected range)

We just need to put in one column the Observed values and in other the expectec values.
