Question 25 3 pts Suppose that the null hypothesis is that the medical treatment is not effective. Suppose that the medical treatment is truly effective, but a researcher does not reject the null hypothesis at the 5-percent level of significance. This researcher o is guilty of a post hoc ergo propter hoc fallacy. o has conducted a test with high statistical power. o has made a Type 1 error. o has made a Type 2 error. Question 26 3 pts Suppose that you have daily closing prices each day for the month of May for the following technology stock prices: Apple, Google, and Amazon. This data set is best described as time-series data. O cross-sectional data. o panel data survey data. Question 27 3 pts Imagine that you regressed the earnings of individuals on a constant, a binary variable ("Male") which takes on the value of 1 for males and is O otherwise, and another binary variable ("Female") which takes on the value of 1 for female and is o otherwise. Because females typically earn less than males, you would expect: o both coefficients to have the same distance from the constant, one above and the other below. the estimated coefficient for Male to have a positive sign, and for Female to have a negative sign. autocorrelation or serial correlation to be a serious problem. o none of the OLS estimators to exist because there is perfect multicollinearity.

Answer 1

21 option ② is right answer Suppose, Eaming = Bot BIMA 32 F t ei 207 008 M to 0.4 F fei =) Earming Here, when F=1, il Fomale, then eaming of individual on average will reduce will reduce by (0-4). Plzz plz -- like my answer
