Explain the differences between Parametric and Nonparametric methods of testing a hypothesis.
Disadvantages of non-parametric tests include: a. For hypothesis testing not estimating effect size b. Degree of confidence may be too high c. May lack power (compared to parametric tests) d. A & C

You are testing the null hypothesis that there is no relationship between two variables, X and Y. From your sample of n = 22, you determine that SSR = 80 and SSE = 20. Construct the ANOVA table, test for model significance at a 0.05 level of significance and state your conclusion, and calculate the coefficient of determination and interpret its meaning.
You are testing the null hypothesis that there is no linear relationship between two variables, X and Y. From your sample of n = 10 , you determine that r=0.55 . a. What is the value of t Subscript STATt? b. At the alpha=0.05 level of significance, what are the critical values?
7. You are testing the null hypothesis that there is no linear relationship between two variables, X and Y. From your sample of n=18, you determine that b1=4.4 and Sb1=1.7. a. What is the value of tSTAT? b. At the α=0.05 level of significance, what are the critical values? c. Based on your answers to (a) and (b), what statistical decision should you make? d. Construct a 95% confidence interval estimate of the population slope, β1. 8. You are testing...
Please use two economic concepts. Thank u. What's the relationship between savings and investment? What's the relationship between investment and economic growth?
You are testing the null hypothesis that there is no linear relationship between two variables, X and Y. You are given the following regression results, where the sample size is 10., Coefficients Standard Error Intercept -1.2 1 X 2 2 a) What is the value of the t test statistic? b) At the α = 0.05 level of significance, what are the critical values? c) Based on your answer to (a) and (b), what statistical decision should you make?
equal" at the 5 percent siguificance level. 2. Still considering the data from "timetofail": redo the test, this time NOT assuming normality of the data.
