A total of 415 children from the United Kingdom and the United States who completed a survey in a recent year were randomly selected. Each student’s country of origin was recorded along with which superpower they would most like to have: the ability to fly, ability to freeze time, invisibility, superstrength, or telepathy (ability to read minds). The data are summarized in the following table.

a. What proportion of students in the sample are from the United States?

b. Find the distribution of superpower preference for the students in the sample using relative frequencies.

c. What percent of students in the sample are from the United Kingdom and prefer telepathy as their superpower preference?
