A candy manufacturer sells bags of chocolate treats that are supposed to be half dark chocolate and half milk chocolate. The CEO opens a bag of the chocolate treats and tells his factory supervisor that he thinks that the types of chocolate are not evenly split in the bag. The supervisor randomly selects several bags, examines
300
of the chocolates, and finds that
56
%
of the
300
chocolates he examined are dark chocolate.

Use Excel to test whether the true proportion of dark chocolates is different from
50
%
. Identify the p-value, rounding to three decimal places.

Round the z-score to two decimal places.
