QUESTION 5Mixed PracticeRead through the problem below. Then, identify the problem type by stating whether the problem is a “regular" problem ora "CLT" problem. Then identify the direction by stating whether it is a "forwards" or a "backwards" problem. Then, solvethe problem. Round standard error vlaues to the nearest thousandth and z-scores to the nearest hundredth whenevernecessary.Suppose the heights of the mountains in a particular mountain range are normally distributed with a mean of u =4,410 feet and a standard deviation of o =feet and 5,100 feet tall?354 feet. What proportion of mountains in this range are between 3,800Туре:Direction:Only find py and ox if the type is "CLT."

ONLY DO PART A Burning fuels in power plants and motor vehicles emit carbon dioxide (CO2), contributing to global warming. The table at the right displays CO2 emissions per person from countries with at least 20 million populations. (a) What is the variable of interest? How do you classify it? (b) Make a histogram of the data using classes of width 2, starting at 0. Show the frequency distribution table and create the Histogram of the data. Be mindful of submitting a correct graph. (c) Describe the shape, center, and spread of the distribution. Which countries are outliers? For a description of the shape, center, and spread, put your response in paragraph form. Select the most appropriate measure of center and measure of spread to describe the distribution. Also, do not forget to interpret the values based on the given context. Lastly, do not forget to include the unit of measurements. For outliers, show your method of how you were able to determine these. What can you say about…
It is thought that prehistoric Indians did not take their best tools, pottery, and household items when they visited higher elevations for their summer camps. It is hypothesized that archaeological sites tend to lose their cultural identity and specific cultural affiliation as the elevation of the site increases. Let x be the elevation (in thousands of feet) for an archaeological site in the southwestern United States. Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a given elevation. Suppose that the following data were obtained for a collection of archaeological sites in New Mexico: x 5.00 5.25 5.75 6.75 7.00 y 8 15 13 49 71 Find the equation of the least squares line .
