Regifting is defined as the act of taking a gift that has been given to you and presenting it as a gift to someone else. According to survey conducted by American Express regarding consumer spending, 79% of the respondents felt that it was socially acceptable to re-gift during the holiday season (big sigh of relief). Suppose a random sample of 10 holiday shoppers was selected.

a. What is the probability that nine shoppers from this sample felt that regifting was socially acceptable?

b. What is the probability that more than seven shoppers from this sample felt that regifting was socially acceptable?

c. What is the probability that less than 10 shoppers from this sample felt that regifting was socially acceptable?

d. What are the mean and standard deviation for this distribution?

e. Construct a histogram for this distribution.
