In a study of mp3 player popularity, 22% of people in a random sample of 1100 americans age 12 and older indicated that they owned an mp3 player. the owners were 26% of the males and 18% of the females. suppose that there were the same number of males and females in the sample of 1100. (use a statistical computer package to calculate the p-value. round your test statistic to two decimal places and your p-value to four decimal places.)

z =

p =
