Consider the population regression of earnings against two binary variables: whether a worker is married (married, where married=1 if the person is married, 0 otherwise) and the worker's gender (female, where female=1 if the person is female, 0 otherwise), and the product of the two binary variables: $Earnings_i = \beta_0 + \beta_1 female_i + \beta_2 married_i + \beta_3 female_i \times married_i + u_i$ You believe that married people earn, on average, more than not married people and you believe that men earn, on average, more than women. You further believe that the marriage premium (difference in average earnings between married and not married people) is larger for men than for women. Hence, you expect $\beta_1$ to be [Select] , $\beta_2$ to be [Select] , and $\beta_3$ to be [Select]

Question 7 of 8 (2.22)/(4) Table 1 shows data on whether or not a treatment relieved pain for patients. \table[[,Treatment,Placebo,Total],[Relleved pain,42,21,63],[\table[[Did not relieve],[pain]],39,54,93],[Total,81,75,156]] Table 1 is the treatment significantly better than the placebo? Test whether the treatment is significantly better than a placebo at relieving pain. The patients were randomly allocated to the two groups and the experiment was double-blind. Use subscripts 1 for the treatment group and 2 for the placebo group. Your answer is partially correct. (a) Find the relevant sample proportions in each group and the pooled proportion. Round your answers to three decimal places, If necessary. hat(p)_(1)=◻ hat(p)_(2)= hat(p)=◻ eTextbook and Media Hint Your answer is correct. (b) State the null and alternative hypotheses. eTextbook and Media Hint Your answer is partialiv correct. (c) Give the test statistic and the p-value. Round your answer for the test statistic to two decimal places and your answer for the pevalue to three decimal places. teststatistic = ◻ p value ◻ What is the conclusion?

Use the t-distribution to find a confidence interval for a difference in means $\mu_1 - \mu_2$, given the relevant sample results. Give the best estimate for $\mu_1 - \mu_2$, the margin of error, and the confidence interval. Assume the results come from random samples from populations that are approximately normally distributed. A 99% confidence interval for $\mu_1 - \mu_2$ using the sample results $\bar{x}_1 = 79.5$, $s_1 = 11.5$, $n_1 = 25$ and $\bar{x}_2 = 62.0$, $s_2 = 8.4$, $n_2 = 20$ Enter the exact answer for the best estimate and round your answers for the margin of error and the confidence interval to two decimal places. Best estimate = Margin of error = Confidence interval: to
