Question

1) Find the regression equation for the given table below. (Round to the nearest tenth) (TYPE THE ACTUAL REGRESSION EQUATION!) (DO NOT TYPE ANY UNNECESSARY SPACES!) for example: y=7.85+0.088x
Altitude        | 3 |10 | 14| 22 |28 |31 |33
Temperature |57 |37 |24 |-5 | -30 |-41 |-54

2) Find the p-value if the following information is given below. (Round to the nearest ten-thousandth)

Test Statistic z = 2.50

Claim is that p ≠ 2/3

∝ =0.05

3) Find the p-value if the following information is given below. (Round to the nearest ten-thousandth)

Test Statistic z = 2.00

Claim is that

4)

Find the p-value if the following information is given below. (Round to the nearest ten-thousandth)

Test Statistic z = -1.23

Claim is that

Answer 1

I am assuming that the test considered is two sided as it is not apparent in the question.

3. For Z=2, the p-value is P(|z|>2) for z to be standard normal density. So p-value is 0.045500

Claim: The null hypothesis is rejected.

4. For z=-1.23, again the p-value is: 0.2186971= 0.2187

Claim: The null hypothesis can’t be rejected as there isn’t enough evidence against null
