Dima020 [189]

Answer:

The P-value for this test is P=0.00006.

Step-by-step explanation:

We have a matched-pair test, with a test statistic t=-14.9.

The degrees of freedom in a sample of 5 students is:

df=n-1=5-1=4

For a  t=-14.9 and 4 degrees of freedom, a left-tail test will have a P-value of:

P-value=P(t_4

The claim is that the new unit on taking square roots is helping students to learn. This test concludes that there is statistical evidence to support the claim that the new unit is helping students to learn.

shutvik [7]
So u have 9/2 Multiply those 2 numbers and you get 18 no (b+35) B would be whatever number that would go with 18 to make 35 Ex: 18+_=35↪18+17=35 So your answer is 17 (Hope I helped but If I didn't may God be with you for more help)
