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.
please quickly thanks !
In the p-value approach to hypothesis testing, we reject the null hypothesis if O p-value > 0.05 O p-value 0.05 O p-value 0.05 O p-value < 0.05

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

4. From experience it is known that a certain brand of tyre lasts, on average, 15,000 miles with standard deviation 1250. A new compound is tried and a sample of 120 tyres yields an average life of 15,150 miles, with the same standard deviation. Are the new tyres an improvement? Use the 5% significance level. Show hypothesis testing by step-by-step.
