Can a low barometer reading be used to predict maximum wind
speed of an approaching tropical cyclone? Data for this problem are
based on information taken from weatherwise. For a random sample of
tropical cyclones, let x be the lowest pressure as a cyclone
approaches and let y be the maximum wind speed of the
cyclone.

a) The scatter diagram is given by,
b) Here we can see that, there is strong negative correlation .
c)
= -0.99
Here value of correlation coefficient is negative and it is close to 1. So we can say that there strong negative correlation between x and y. This imply that as value of x increases the value of y decreases.

Is the magnitude of an earthquake related to the depth below the surface at which the quake occurs? Let x be the magnitude of an earthquake (on the Richter scale), and let y be the depth (in kilometers) of the quake below the surface at the epicenter. x 3.1 4.6 3.3 4.5 2.6 3.2 3.4 y 4.8 9.8 11.2 10.0 7.9 3.9 5.5 (a) Make a scatter diagram of the data.

It is thought that basketball teams that make too many fouls in a game tend to lose the game even if they otherwise play well. Let x be the number of fouls more than (i.e., over and above) the opposing team. Let y be the percentage of times the team with the larger number of fouls wins the game. х 33 26 y48 44 14, Ey 151, x2 = 66, Ey2 = 6005, Exy Complete parts (a) through (e), given...
