12) An economist is studying the job market in Denver area neighborhoods. Let x represent the total number of jobs in a given neighborhood, and let y represent the number of entry-level jobs in the same neighborhood. A sample of six Denver neighborhoods gave the following information (units in hundreds of jobs). x14 30 48 28 50 25 y 2 4 5 5 9 3 Complete parts (a) through (e), given Σx = 195, Σy = 28, Σx2 = 7309, Σy2 = 160, Σxy = 1053, and r ≈ 0.847. (b) Verify the given sums Σ

Question 1 A sample of 40 endangered species was obtained and the length of time (in months) since being placed on the list was recorded for each species. A stemplot of these data follows. In the stemplot 5|2 represents 52 months. Please explain how to solve. Reference: Ref 1-7 The number of species in the sample that have been on the list for more than 6 years is 10. 12. 14. 18.

Five males with an​ X-linked genetic disorder have one child each. The random variable x is the number of children among the five who inherit the​ X-linked genetic disorder. Determine whether a probability distribution is given. If a probability distribution is​ given, find its mean and standard deviation. If a probability distribution is not​ given, identify the requirements that are not satisfied.

In which of the following situations is the Central Limit Theorem NOT applicable? Select one: a. When the sample is small and the population is normal b. When the sample is small, below 30 and the population is not normal c. When the sample is large and the population is normal d. When the sample is large, above 30 and the population is not normal e. None of the others

50% of Reese’s Pieces candies are orange. The Reese’s Pieces applet lets you simulate draws from a hypothetical population of Reese’s Pieces and take data on the orange candies in your sample(s). (This applet was created by Professors Allan Rossman and Beth Chance at Cal Poly, San Luis Obispo.) http://www.rossmanchance.com/applets/OneProp/OneProp.htm?candy=1  If you do not immediately see the “Reese’s Pieces” simulation, scroll down the page and in the bottom left-hand corner you need to ‘click’ where prompted to default to the “Reese’s Pieces” simulation. 1)1) Use the applet to draw 25 candies and calculate the proportion of orange candies. Do this […]
