We would consider "favorite sport to watch on television" to be a_ variable. 2. If you were to create a graph in order to display the data shown in the above table, would it be more appropriate to construct a bar graph or a pie chart, or could you use either of these types of graphical displays? Please explain the reason for your answer. 3) Another survey was conducted about favorite television sports. This time, the sample consisted of 600 elementary school children, and each child was asked to list all the different sports they enjoyed watching on television. The results of the survey are displayed in the table below.

Please explain the reason for your answer. 4) In 2017, Gallup conducted a poll about sports. A random sample of 1,049 adults were surveyed, and 37% indicated that football was their favorite sport to watch. Other popular sports to watch were basketball (11%), baseball (9%), and soccer (7%).

Each tile has a letter printed on it and a point value, and players earn points based on adding the point values of the words they form. Placing their tiles on select squares on the game board can result in earning bonus points. At the end of the game, the player with the most points is the winner. Every year, several Scrabble games are played at Scrabble tournaments across the country. The histograms below show the distribution of the number of points earned by the winning players in a random sample of 100 Scrabble tournament games, and by the losing players in a random sample of 100 Scrabble tournament games. Frequency 350 400 450 500 Points earned by winning player the 550 600 650 200 240 280 320 Points earned by losing player E) We would consider "points earned by winning player" and "points earned by losing player" to be variables. F) The distribution of the variable "points earned by winning player" is skewed to the 360 while the distribution of the variable "points earned by losing player" is skewed to G) Which distribution above "points earned by winning player" or "points earned by losing player" has more variability? Please explain. H) In Chapter 11, you learned that one way you can describe a histogram is by focusing on the midpoint, or the "typical value" in the histogram. For "points earned by winning player," the midpoint is about points; for "points earned by losing player," the midpoint is about points. Part 3: What's wrong? I) The Economic Research Service (ERS) from the United States Department of Agriculture (USDA) uses information from different retail establishments to provide estimates of the average price per pound (in dollars) of different fruits and vegetables. These prices are used when publishing the Dietary Guidelines for Americans in order to show individuals how much it will cost them to maintain a healthy diet. The histogram below shows the distribution of the estimated average prices per pound, in 2016, of 58 fruits and vegetables. Each of the following descriptions of this distribution is incorrect. Explain what is wrong with each description. 20 Estimated average price per pound (in dollars) A. A majority of the estimated average prices are less than $1.50. B. There are five fruits and vegetables with estimated average prices of exactly $3.00 per pound. C. There is one fruit or vegetable in this data set that has an estimated average price of $7.00 per pound. D. We can see, by looking along the x-axis, that estimated average prices start low at the beginning of 2016 and get higher later in 2016. J) How do Americans feel about legalizing marijuana? A survey of a representative sample of Americans, from four regions across the United States, yielded the results presented in the accompanying graph. Sam looks at this graph and describes the distribution as being "skewed to the left."
