UNO [17]

Answer:

P-value = 0.009997                                                  

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 24

Nature of test: One-tailed test(Left tailed test)

t_{\text{statistic}} = -2.50

We have to calculate the p-value.

Degree of freedom = n - 1 = 23

We calculate the p-value from the table corresponding to t score -2.50 and degree of freedom 23.

P-value = 0.009997

0.009997 is the  probability of a value being to the left of a number that has a student-t statistic of –2.50.

So you want to add together 4, 6, 11, and 9.

So to make it easier, I would first add together 4 and 6, and 11 and 9.

4 and 6 added together is 10

11 and 9 added together is 20

So, just 20 + 10, or 30.
