question Refer to the Table. What is the conditional probability of “high income,” given “never”? $$ \begin{array}{|lcccc|} \hline \text { Viewing Frequency } & \text { High INCOME } & \text { Middle INCOME } & \text { Low INCOME } & \text { TOtals } \\ \hline \text { Regular } & 0.10 & 0.15 & 0.05 & 0.30 \\ \text { Occasional } & 0.10 & 0.20 & 0.10 & 0.40 \\ \text { Never } & 0.05 & 0.05 & 0.20 & 0.30 \\ \text { Totals } & 0.25 & 0.40 & 0.35 & 1.00 \\ \hline \end{array} $$ Verified answer
question The following regression was fitted by least squares to 32 annual observations on time-series data: $$ \log y_t=4.52-\underset{(0.28)}{0.62} \log x_{1 t}+\underset{(0.38)}{0.92} \log x_{2 t}+\underset{(0.21)}{0.61} \log x_{3 t} $$ $$ \begin{aligned} &+0.16 \log x_{4 t}+e_t \quad \bar{R}^2=0.683 \quad d=0.61 \\ &\text { (0.12) } \\ & \end{aligned} $$ where $y_t=$ quantity of U.S. wheat exported $x_{1 t}=$ price of U.S. wheat on world market $x_{2 t}=$ quantity of U.S. wheat harvested $x_{3 t}=$ measure of income in countries importing U.S. wheat $x_{4 t}=$ price of barley on world market The numbers below the coefficients are the coefficient standard errors. a. Interpret the estimated coefficient on $\log x_{1 t}$ in the context of the assumed model. b. Test at the $5 \%$ level the null hypothesis that, all else being equal, income in importing countries has no effect on U.S. wheat exports against the alternative that higher income leads to higher expected exports. (Ignore, for now, the Durbin-Watson $d$ statistic.) c. What null hypothesis can be tested by the $d$ statistic? Carry out this test for the present problem, using a $1 \%$ significance level. d. In view of your finding in part c, comment on your conclusion in part b. How might you proceed to test the null hypothesis of part b?

question Imagine that you are being interviewed for a job as a financial adviser for an investment firm. The interviewer says the company’s average clients with the most savings are over the age of $55$. However, this group includes the most conservative investors. Your job would be to encourage this group to invest in high-risk stocks, which would bring in more commissions but could possibly lead to major losses for the investors. Should you take the job?

This helps you conclude that the outcomes can be attributed to the independent variable.
What is the most important reason for Random assignment?Random assignment helps ensure that members of each group in the experiment are the same, which means that the groups are also likely more representative of what is present in the larger population.
What is random assignment in an experiment quizlet?-Random assignment means that each participant has an equal chance of being placed into any group. It limits the effects of confounding variables based on differences between people. -Using random assignment diminishes the chance that participants in the two groups differ in any meaningful way.
What is random assignment and why is it used?Random assignment of participants helps to ensure that any differences between and within the groups are not systematic at the outset of the experiment. Thus, any differences between groups recorded at the end of the experiment can be more confidently attributed to the experimental procedures or treatment.
