Have you wondered how Internet connection speed varies around the globe? The file ConnectionSpeed contains the mean connection speed, the mean peak connection speed, the % of the time the speed is above 4 Mbs, and the % of the time the connection speed is above 10 Mbps for various countries.

Source: Data extracted from bit.ly/1hHaHVD.

Answer (a) through (c) for each variable.

a. Compute the mean, median, first quartile, and third quartile.

b. Compute the range, interquartile range, variance, standard deviation, and coefficient of variation.

c. Construct a boxplot. Are the data skewed? If so, how?

d. Compute the coefficient of correlation between mean connection speed, mean peak connection speed, percent of the time the speed is above 4 Mbps, and the percent of the time the connection speed is above 10 Mbps.

e. Based on the results of (a) through (c), what conclusions can you reach concerning the connection speed around the globe?

f. Based on (d), what conclusions can your reach about the relationship between mean connection speed, mean peak connection speed, percent of the time the speed is above 4 Mbps, and the percent of the time the connection speed is above 10 Mbps?
