Consider the following scenario: The significance level is 5% Of all tested hypotheses, 40% are true The statistical power is 40% What is the probability of the finding being true, given that the estimate is statistically significant? (State your answer as percentage without the percent symbol. For example, if you think the correct answer is 10%, just state 10)
5 Suppose in a test of hypothesis the probability value (p-value) is 0.0788. Then you should, a not reject H₀ at α = 0.10. b reject H₀ at α = 0.05. c reject H₀ at α = 0.05, but not reject H₀ at α = 0.10. d reject H₀ at α = 0.10, but not reject H₀ at α = 0.05.
a. How to derive the variance and estimates of ols, and which steps in the derivation process require assumptions, list them.b. Under the classic OLS model. Given the R∧2 as well as the adjusted R∧2, discuss this two R-squared differences, advantages and disadvantages and their different roles.
You are trying to determine whether or not variables x2 and x3 jointly affect y. You set up a null and alternative hypothesis appropriate to this question. Before forming your test statistic, what are the two models you need to estimate? None of these is the correct pair of models to estimate. y = Bo + B1x1 + B2x2 + B3x3 + B4x4 + u and y = Bo + v y = Bo + B1x1 + B2x2 + B4x4 + w and y = Bo + B1x1 + B3X3 + B4X4 + e y = Bo + B1x1 + B2x2 + B3x3 + B4x4 + u and y = Bo + B1x1 + B4x4 + v

assume there are two types of workers, low- and high-ability, andlet 0 = 0.25 be the proportion of high-ability workers in the population. Assume their marginalproductivity and, therefore, their wages are wh = $20 and wl = $16, and that both types canuse college education to signal high ability. The cost of college education for low-ability workersis cl = $5 whereas the cost for high-ability workers is ch = $2. Consider the wage for both types of workers and the high-ability workers’ college cost, ch. For which values of 0 (the proportion of high-ability workers in the population) do the high-ability workers prefer the separating equilibrium over the pooling equilibrium? (a) Any 0 > 1/2(b) Any 0 < 1/2 (c) Any 0 < 3/4(d) Only when 0 = 1

When conducting a hypothesis test, you obtain a large p-value. This implies ... a- that the observed value is consistent with the null hypothesis b- a rejection of the null hypothesis c- the observed value is larger than cut-off value specified by the test d- that the t-satistic is large What is the answer?
