In the 1992 presidential election, Alaska's 40 election districts averaged 1833 votes per district for President Clinton. The standard deviation was 558. (There are only 40 election districts in Alaska.) The distribution of the votes per district for President Clinton was bell-shaped. Let X = number of votes for President Clinton for an election district. (Source: The World Almanac and Book of Facts) Round all answers except part e. to 4 decimal places.a. What is the distribution of X? X ~ N(Correct,Correct) b. Is 1833 a population mean or a sample mean? Select an answer Sample Mean Population Mean c. Find the probability that a randomly selected district had fewer than 1915 votes for President Clinton. d. Find the probability that a randomly selected district had between 1813 and 1922 votes for President Clinton. e. Find the third quartile for votes for President Clinton. Round your answer to the nearest whole number.
An evaluation was recently performed on brands and data were collected that classified each brand as being in the technology or financial institutions sector and also reported the brand value. The results in terms of value (in millions of dollars) are shown in the accompanying data table. Complete parts (a) through (c). Click the icon to view the data table. a. Assuming the population variances are equal, is there evidence that the mean brand value is different for the technology sector than for the financial institutions sector? (Use α = 0.05.) Determine the hypotheses. Let μ, be the mean brand value for the technology sector and μ₂ be the mean brand value for the financial institutions sector. Choose the correct answer below. 4₁ OA.
