Test the hypothesis: H0: β2 = 1 against H1: β2 > 1. Which test do you use? And why? What are the underlying assumptions of the test(s) you use? Consider the following regression output:Ŷt= 0.2033 +0.656Xtse (0.0976) (0.1961)r² = 0.397 RSS=0.0544 ESS = 0.0358Where:Y = labor force participation rate (LFPR) of women in 1972 andX = LFPR of women in 1968. The regression results were obtained from a sample of 19 cities in theUnited States.

Given: The regression equation is: Yt^=0.2033+0.656Xt Where, β1=0.2033β2=0.656 n=19 Also,…

Answered: Consider the following regression…

Life on Other Planets Forty-three percent of people believe that there is life on other planets in the universe. A scientist does not agree with this finding. He surveyed 120 randomly selected individuals and found 69 believed that there is life on other planets. At α=0.01, is there sufficient evidence to conclude that the percentage differs from 43% ?

Scientist Irish used a paired t-test to test the effectiveness of a drug she is developing. She obtained a p-value = 0.005 (she used α = 0.05). Suppose the drug actually works. Which of the following statements is correct? Irish should not have rejected the null hypothesis because the p-value is too large. Type I error occurred. Type II error occurred. There was no error.
