Per Capita Income of Delaware Residents In a recent year, Delaware hadthe highest per capita annual income with $51,803. If o = $4850, answer the followingquestions. Assume that the sample is taken from a large population and thecorrection factor can be ignored. Round intermediate z-value calculations to twodecimal places and the final answers to at least four decimal places.Part: 0/ 2Part 1 of 2What is the probability that a random sample of 40 state residents had amean income greater than sso0,800?P(x > 50,800)-

Question 3 7 pts An investigator wishes to test the hypothesis that "blondes have more fun." To investigate, he develops the Subjective Report of Fun Scale (high scores indicate more fun), selects 13 brunettes at random and administers the SRFS to them. He then bleaches all 13 subjects' hair blonde, waits two weeks, and administers the SRFS again. Data are below. Do blondes have more fun?
