A matched pairs experiment compares the taste of instant with fresh-brewed coffee. Each subject tastes two unmarked cups of
coffee, one of each type, in random order and states which they prefer. Of the 50 subjects who participate in the study, 32
preferred the fresh-brewed coffee.
Test the claim that a majority of people preferred the taste of fresh-brewed coffee. Report the large-sample z statistic and its
P-value. Draw a sketch of a standard Normal curve and mark the location of your z statistic. Shade the appropirate area that
corresponds to the P-value.
Give the z statistic to two decimals and give the P-value to three decimal places.
