For a random sample of 263 professionals, the correlation between their age and their income was found to be 0.17. You are interested in testing the null hypothesis that there is no linear relationship between these two variables against the alternative that there is a positive relationship. What is your conclusion in testing H0: Ļ=0 vs H1: Ļ>0 at Ī± = 0.05 ? a. Fail to reject H0 b. Reject H0 c. Not enough information to draw a conclusion d. None of the above

Step 1
In this case, the null hypothesis (H0) is that there is no linear relationship between age and income among professionals, which means the population correlation coefficient (Ļ) is 0. The alternative hypothesis (H1) is that there is a positive linear relationship, Show moreā¦

You are testing the null hypothesis H0: Ć°ĀÅā” = 16. a) Which 95% confidence intervals would lead to a decision to reject the null hypothesis? Select all that apply. (-23.2, -19) (-2.44, 4.24) (37.57, 46.87) (12.4, 20.1) (14.07, 25.85) b) Which t-statistics would lead you to reject the null hypothesis? Select all that apply. 1.66 -1.33 -4.91 0.74 8.62 c) Which p-values would lead you to reject the null hypothesis? Select all that apply. 0.0380 0.6820 0.19 0.4584 0.0105

Use the data in WAGE2 for this exercise. (i) Consider the standard wage equation $$\log (wage)=\beta_{0}+\beta_{1} e d u c+\beta_{2}$exper$+\beta_{3}$tenure$+u$$ State the null hypothesis that another year of general workforce experience has the same effect on log(wage) as another year of tenure with the current employer. (ii) Test the null hypothesis in part (i) against a two-sided alternative, at the 5$\%$ significance level, by constructing a 95$\%$ confidence interval. What do you conclude?
