Question
A scientist claims that there is a linear relationship between a lake’s flow rate and its runoff factor. The scientist collected data and used the data to test the claim that there is a linear relationship at a significance level of α=0.05α=0.05. The scientist tested the following hypotheses.
H0: β1=0
Ha: β1≠0
The scientist found a p-value of 0.02 for the test. Which of the following is a correct conclusion about the scientist’s claim?
A. The null hypothesis is rejected since 0.02<0.05. There is sufficient statistical evidence to suggest that there is a linear relationship between a lake’s flow rate and runoff factor.
B. The null hypothesis is not rejected since 0.02<0.05. There is sufficient evidence to suggest that there is a linear relationship between a lake’s flow rate and runoff factor.
C. The null hypothesis is rejected since 0.02<0.05. There is not sufficient evidence to suggest that there is a linear relationship between a lake’s flow rate and runoff factor.
D. The null hypothesis is not rejected since 0.02<0.05. There is not sufficient evidence to suggest that there is a linear relationship between a lake’s flow rate and runoff factor.
E. The null hypothesis is accepted since 0.02<0.05. There is sufficient evidence to suggest that there is not a linear relationship between a lake’s flow rate and runoff factor.

- In a simple linear regression based on 30 observations, it is found that b1 = 3.57 and se(b1) = 1.36. Consider the hypotheses:H0: β1 = 0 and HA: β1 ≠ 0.a. Calculate the value of the test statistic. (Round your answer to 3 decimal places.) b. Find the p-value. [Hint: The test statistic has a t-distribution with df = 30 – 2. Refer to Chapter 9 of the formula sheet to get the appropriate p-value.] p-value < 0.01 0.01 p-value < 0.02 p-value 0.10 0.05 p-value < 0.10 0.02 p-value < 0.05 c. At the 5% significance level, what is the conclusion? Is the explanatory variable statistically significant? Reject H0; the explanatory variable is significant.

- A mortgage is a type of loan that can be used to purchase a house. A large bank is interested in the relationship between a customers’ years of experience in their current job and the mortgage amount for customers with a mortgage. They selected 100 customers with a mortgage at random and used the data to test the claim that there is a negative linear relationship between years of experience in the current job and mortgage amount. The following hypotheses were used to test the claim. H0:β1=0Ha:β1<0 The test yielded a t-value of −3.865 with a corresponding p-value of 0.0001. Which of the following is the correct interpretation of the p-value? If the alternative hypothesis is true, the probability of observing a test statistic of −3.865 or smaller is 0.0001.
