Which function in Excel is used to perform a test of independence? a. T.TEST b. CHISQ.TEST c. NORM.S.DIST d. Z.TEST
denis23 [38]

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.

Lindsay and Lorraine are trying to match the jump rope world record. Together, they need to jump 48 times in a row. Lindsay has
Sunny_sXe [5.5K]

Answer:  21

Step-by-step explanation:

Given : Lindsay and Lorraine are trying to match the jump rope world record.

Number of jumps they need to jump together in a row =  48

Lindsay has gotten 14 jumps in a row, and Lorraine has gotten 13.

Total jumps = 14+13=27

Let 'j' be the number of more jumps they need to match the record.

j= Total jumps needed - Total jumps they already gotten

⇒  j= 48-27

⇒  j= 21

Hence, they need 21 more jumps to match the record.
