he pandemic, the price of gasoline varies constantly from the last two months. However, youobserved that local gas stations charge higher price. You want to test your hypothesis that local gas stations are charging much more than the national average price for  What is your claim about this problem? What is the null hypothesis of this study?

The results obtained above were primarily due to the mean for the third treatment being noticeably different from the other two sample means. For the following data, the scores are the same as above except that the difference between treatments was reduced by moving the third treatment closer to the other two samples. In particular, 3 points have been subtracted from each score in the third sample. Before you begin the calculation, predict how the changes in the data should influence the outcome of the analysis. That is, how will the F-ratio for these data compare with the F-ratio from above? Treatment A Treatment B Treatment C 1 4 3 2 1 1 3 2 7 2 3 4 F-ratio = p-value = Conclusion: O These data do not provide evidence of a difference between the treatments O There is a significant difference between treatments

In the setting of Multiple Regression Model (MRM), what do we mean by linear statistical models? Give example of a non-linear MRM with two predictors.

Illustrate the Regression Discontinuity Estimators?

Help me please

In comparing two multiple regression models, one with variables that are a subset of the other, bigger model’s variables, to infer which model is superior, I get confused in looking at R-squared, adjusted R-squared, and F-statistic values. What’s the difference among them and is one of these preferable to the others?  Thanks.

jake suspects that individuals with an optimistic world view live longer than individuals with a pessimistic view. Sate the research hypothesis the null hypothesis cases independent variable dependent variable

On average, a sample of n = 36 scores will provide a better estimate of the population mean than a sample of n = 49 scores from the same population.

Please let me know if I calculated relative risk correctly. Thank you for your assistance.
