only typing and drw scatter plot In baseball, is there a linear correlation between batting average and home run percentage? Let xrepresent the batting average of a professional baseball player. Let y represent the home runpercentage (number of home runs per 100 times at bat). Suppose a random sample of baseballplayers gave the following information. x 0.251 0.259 0.29 0.265 0.269 y 1.3 3.7 5.8 3.9 3.7 Make ascatter diagram for the data. Draw the line that best fits the data. a. b. c. d. e.

Here is a data set: 396 417 438 444 456 457 457 478 510 521 547 559 589 591 594 595 597 601 602 618 620 660 662 664 667 700 814 831 Construct a frequency distribution table for this data set. • Number of classes: 10 • Use a "nice" class width, such as a multiple of 5 or 10. Label classes using interval notation. o For example, if the class is 70-79, label it as (70,79]. The lower class limit should be a multiple of the class width. o For example, if the class width is 10, the lower class limit should be a number like 30 or 40 (depending on the data).

A least squares regression model performed to predict the selling price of houses found the following equation: Pricê = 169.328+35.3Area + 0.718Lotsize - 6543Age where Price is in dollars, Area is in square feet, Lotsize is in square feet, and Age is in years. The R2 is 0.92. One of the following interpretations is correct. Which is it? Explain why. a.) Each year a house Ages, it is worth $6543 less. b.) Every extra square foot of Area is associated with an additional $35.30 in average price, for houses with a given Lotsize and Age. c.) Every dollar in price means Lotsize increases 0.718 square feet. d.) This model fits 92% of the data points exactly.

SCUBA divers have maximum dive times they cannot exceed when going to different depths. The data in the table below show different depths with the maximum dive times in minutes. (Comma separated lists of the data are also provided below the table to ease in copying the data to R.) Depth in Feet (x) 50 60 70 80 90 100 x: 50, 60, 70, 80, 90, 100 y: 179, 166, 150, 138, 124, 110 Maximum Dive Time in Minutes (y) 179 166 150 138 124 110 1. Find the best fit line for the data. y = + x 2. Graph the scatter plot of the data together with the best fit line using R. (This portion of the problem is not graded.) 3.

The amount of time adults spend watching television is closely monitored by firms because this helps to determine advertising pricing for commercials. Complete parts (a) through (d). (a) Do you think the variable "weekly time spent watching television" would be normally distributed? If not, what shape would you expect the variable to have? OA. The variable "weekly time spent watching television" is likely normally distributed. OB. The variable "weekly time spent watching television" is likely symmetric, but not normally distributed. OC. The variable "weekly time spent watching television" is likely uniform, not normally distributed. O D. The variable "weekly time spent watching television" is likely skewed left, not normally distributed. O E. The variable "weekly time spent watching television" is likely skewed right, not normally distributed.
