An increasing number of people are giving gift certificates as Christmas presents. To measure the extent of this practice, a random sample of people was asked (survey conducted December 26-29) whether they had received a gift certificate for Christmas. The responses are recorded as 1 = No and 2=Yes. Dataset is available on our Quercus webpage (see Datasets, gift-certificates.txt↓). Using R, find a point estimate for the proportion of people who received a gift certificate for Christmas. Round your final answer to four decimal places.
