Here, it is required to write the null and alternative hypotheses:

6 In a test of hypothesis, the symbol α represents: a The level of significance, or the probability of rejecting a true H₀. b The power of the test, or the probability of rejecting a false H₀. c The level of significance, or the probability of not rejecting a false H₀. d The level of significance, or the probability of committing a Type II error.
We are studying the factors that contribute to unemployment at an individual level. UE, unemployment, is our dependent variable and it is a binary variable that takes the value 1 if an individual is unemployed and 0 if they are employed. We have a random sample and we estimate the following model: UE^= 0.508−0.051educ−0.023urban+0.005age(0.122) (0.012) (0.005) (0.002)n=6214, R2=0.474 where educ = an individual’s years of education urban = a dummy equal to 1 if the individual lives in an urban area and 0 otherwise age = an individual’s age in years What is the correct interpretation of the estimated coefficient on education?
Suppose you are a consultant to a fast food chain. The fast food chain is interested in measuring the population variance in the number of customers it has on adaily basis in all its stores in the U.S. However, it is limited in its ability to track this number across all stores and has to select a sample. Think critically about thefollowing questions:1. There are two estimators for the population variance with different levels of bias and variance. Explain how you would go about choosing between thesetwo estimators.2. You are interested in coming up with a 95% confidence interval for the population variance. How would you go about deciding the number of outlets tosample?

2. A city had an unemployment rate of 7%. The mayor pledged to lower this figure and supported programs to decrease unemployment. A group of citizens wanted to test with 0.032 label of significance if the unemployment rate had actually decreased, so they obtained a random sample of 500 citizens to see what proportion of the sample was unemployed. Only 32 citizens in the above sample is still unemployed. What is the probability of Type II error if the actual unemployment rate is 6.5% please don't use software everything needs to be done by hand. Explain because I don't understand my professor.

ADVERSE SELECTIONSomet Health Insurance Company wants to sell a health insurance product for $700 permonth. There is no requirement for healthy people to have insurance coverage. Thecompany conducts a survey to see how different populations respond to the proposed cost.People with no illnesses and disabilities, generally the young and healthy, respond that theydo not spend $700 on healthcare in an entire year, and most feel they would not waste somuch money on premiums when the chance of needing surgery or expensive healthcaretreatments is so small. However, older, sicker people think that $700 per month is a greatdeal, as most of them spend far in excess of this amount on healthcare. It seems like agreat deal for them. What will happen to the costs of the health insurance if only the older, sicker peopleenroll?
Sales of sugar-sweetened beverages at stores in Seattle dropped about 30.5% in the monthsafter the city adopted a tax on such beverages, says a new study that also looked at sales atstores in Portland, which has no such tax.Sales in Portland declined only 10.5%, suggesting sales in Seattle dropped much more thanthey would have without a tax, according to the peer-reviewed study by University of Illinoisat Chicago researchers.The study’s results are the first to measure the impact of Seattle’s tax on beverage sales inthe city, and they may bolster claims by supporters that the controversial policy is workingas intended.“From a public health perspective, this is good,” said Jay Krieger, a University of Washingtonprofessor who heads the nonprofit Healthy Food America. “People are purchasing lesssugary drinks, and we know that sugary drinks are associated with heart disease, diabetes,high blood pressure and strokes.”Seattle’s tax of 1.75 cents per fluid ounce, which took effect on Jan. 1,…

A government study found that people who eat chocolate frequently weighless than people who don’t. Researchers questioned 1000 individuals fromCalifornia between the ages of 20 and 85 about their eating habits, andmeasured their weight and height. On average, participants ate chocolatetwice a week and had a body mass index (BMI) of 28. There was anobserved difference of five to seven pounds in weight between those whoate chocolate five times a week and those who did not eat any chocolate atall, with the chocolate eaters weighing less on average. Frequent chocolateeaters also consumed more calories, on average, than people who consumedless chocolate. Based on this summary, would you recommend thatAmerican’s who do not presently eat chocolate, consider eating chocolateup to five times a week if they want to lose weight? Why or why not?Explain.
