Elephants and hippos We removed humans from thescatterplot in Exercise 31 because our species was anoutlier in life expectancy. The resulting scatterplot showstwo points that now may be of concern. The point in theupper right corner of this scatterplot is for elephants, andthe other point at the far right is for hippos.a) By removing one of these points, we could makethe association appear to be stronger. Which point?Explain.b) Would the slope of the line increase or decrease?c) Should we just keep removing animals to increase thestrength of the model? Explain.d) If we remove elephants from the scatterplot, the slopeof the regression line becomes 11.6 days per year. Doyou think elephants were an influential point? Explain.

NFL Pre-SeasonTeams in the National Football League (NFL) in the US play four pre-season games each year before the regular season starts. Do teams that do well in the pre-season tend to also do well in the regular season? We are interested in whether there is a positive linear association between the number of wins in the pre-season and the number of wins in the regular season for teams in the NFL. (a) What are the null and alternative hypotheses for this test? (b) The correlation between these two variables for the 32 NFL teams over the 10 year period from 2005 to 2014 was 0.067. Use this sample (with n=320) to calculate the appropriate test statistic and determine the p-value for the test. Round your answers to two decimal places. (c) State the conclusion in context, using a 5% significance level. Options below: 1. Do not reject H0. We find evidence that there is not a positive linear association between wins in the pre-season and wins in the regular season. 2.

- A team of psychologists studied the concept of visualization in basketball, where players visualize making a basket before shooting the ball. They conducted an experiment in which 20 basketball players with similar abilities were randomly assigned to two groups. The 10 players in group 1 received visualization training, and the 10 players in group 2 did not. Each player stood 22 feet from the basket at the same location on the basketball court. Each player was then instructed to attempt to make the basket until two consecutive baskets were made. The players who received visualization training were instructed to use visualization techniques before attempting to make the basket. The total number of attempts, including the last two attempts, were recorded for each player. The total number of attempts for each of the 20 players are summarized in the following boxplots. (a) Based on the boxplots, did basketball players who received visualization training tend to need fewer attempts…arrow_forwardJustify is it true or false?
