A poll uses responses to several questions to calculate a "Happiness" index that measures overall happiness. An article included the happiness index for the 7 years between 2008 and 2016. Also included in the article were the percentages of people who responded "somewhat agree" or "strongly agree" to thefollowing statements.Statement1 (happy with life) 1: At this time, I'm generally happy with my life.Statement 2 (won't benefit): I won't get much benefit from the things that I do anytime soon.Year2008200920102011201320152016HappinessIndex32363434323530Happy withLife Statement(percentagesomewhat orstrongly agree)78837881798282Won't BenefitStatement(percentagesomewhat orstrongly agree)35373537433542(a) Calculate the value of the correlation coefficient for Happiness index and the response to the Happy with life statement.

Suppose that a polling company surveyed 600 people about how much time they spend watching television each day. The results of this survey were compiled and used to create this relative frequency histogram. Assume that all percentages shown in the histogram are whole numbers. Each of the bars in this histogram includes only the left endpoint of the class except for the last bar, which also includes the right endpoint. What percentage of respondents said that they watch television at least six hours per day? How many respondents said that they watch television between three and five hours per day?
(3) Look at the boxplot below, which shows data for the selling price of homes in acertain neighborhood.a. What was the typical selling price? (This should be one number.)b. The cheapest 25% of homes sold for what range of prices? (This should be a rangeof values.) c. The middle 50% of homes sold for what range of prices? (Again, this should be arange of values.)
Identify the type of observational study (cross-sectional, retrospective, or prospective) described below. A research company uses a device to record the viewing habits of about 5000 households, and the data collected over the next 6 years will be used to determine whether the proportion of households tuned to a particular news program decreases. Which type of observational study is described in the problem statement? A retrospective study A prospective study A cross-sectional study

You saw back in Chapter 2 that the mean, median, mode, and midrange are used to indicate where data is centered in a data set, or in other words what a typical value in the set is. A question that is often asked is, "If they're all supposed to do the same thing, why is there more than one?" Isn't one enough? In this exercise, you will be given two small sets of data. For each set, a. find the mean, median, mode and midrange b. in your opinion, decide which of the measures BEST represents all the values in the set (best indicates a typical value), and which one does this the WORST. c. post your responses and justify them by explaining why Don't forget to respond to at least one of your classmate's posts. With this exercise, "more is better." I'll elaborate after the deadline. • Set A: the salaries of 10 employees at a company (in thousands of dollars): 50, 50, 50, 50, 50, 50, 50, 50, 50, 500 • Set B: the grades of 9 students on an exam: 20, 25, 30, 35, 40, 45, 100, 100, 100
