A random sample of 100 students at a high school was asked whether they would ask their father or mother for
help with a homework assignment in science. A second sample of 100 different students was asked the same
question for an assignment in history. If 43 students in the first sample and 47 students in the second sample
replied that they turned to their mother rather than their father for help, test the claim whether the difference
between the proportions is due to chance. Use α = 0.02.
