A concern is that this new technology might impact on the distance that the ball travels. To compare distances, Sarah, a company researcher, conducts an experiment where 20 current balls and 20 new balls are subjected to distance tests, using a mechanical hitting device for consistency. The results of the tests, with distances given to the nearest metre, are given in Table 1.

Your section concerns the effect of wildfires on natural areas. Your supervisor asked you to analyze the temporal trend in wildfires. In particular, she is interested in the following associations:1. Has the number of wildfires per year increased?2. Has the total burned area (in acre) per year increased?3. Has the burned area (in acre) per fire increased?The accompanied data file contains the number of wildfires, total burned area, and burned area per fire in the U.S. from 2000 to 2019. Question 1. Using Excel, create three scatter plots which show each association (year and number of wildfires, year and total burned area, and year and burned area per fire). Clearly label the graphs. Note that year should be on the x-axis. Attach the scatterplot to this report. Refer to the textbook 12.2. (15 pts.) Question 2.

The following graph illustrates the results of a study by Fritsches et al. (2005) that measured how the ability of swordfish retinas to detect rapid motion, measured by the flicker fusion frequency, changes with eye temperature. 50 40- 30- 20 10- 0. 10 15 20 25 Eye temperature ("C) Whitlock & Schluter, The Analysis of Biologica Deta Se 2020 W.H. Freeman and Company The 20 points in the graph were obtained from measurements of 6 swordfish. Can you treat the 20 measurements as a random sample? No, because the selection of the measurements is not independent. Yes, because otherwise the results would not be published. Yes, because the researchers can make a scatter plot only based on the random sample. ONo, because the researchers should have studied at least 10 swordfish.
