a. Compute the mean and standard deviations for each of the tire pressure columns. b. Draw or create and show a scatterplot for this data. Use left tire pressure as the horizontal x-axis and right tire pressure as the vertical y-axis. c. Count the number of times both the left and right tires are above their respective means for the same automobile.

Question

Transcribed Image Text:a. Compute the mean and standard deviations for each of the tire pressure columns.
b. Draw or create and show a scatterplot for this data. Use left tire pressure as the horizontal x-axis
and right tire pressure as the vertical y-axis.
c. Count the number of times both the left and right tires are above their respective means for the same
automobile.
d. Count the number of times the left tire is above its mean and the right tire is below its mean for the
same automobile.
e. Compute the covariance and correlation coefficient r between the right tire pressure.
f. How do you know the relationship between pressure in the left and right tires is positive.
g. What value would a correlation coefficient (r) be close to if there was no (linear) relationship between
the 2 tire pressures?

Transcribed Image Text:Tire pressure (in kPa) was measured for the left and right front tires on a sample of 6 automobiles.
Left (x) Right (y)
