In 1996, 32% of university undergraduate students had atleast
one tattoo. A health practioner obtains a random sample of 1020
university undergraduates and finds that 342 have atleast one
tattoo. Has the proportion of university undergraduates with
atleast one tattoo changed sine 1996? Use the a=0.1 level of
significance. What is the conclusion of the hypothesis test at the
a=0.1 significance level?
