Suppose a random sample of 10 holiday shoppers was selected. Complete parts a through d. a. What is the probability that 9 shoppers from this sample felt that regifting was socially acceptable? The probability is. (Type an integer or decimal rounded to four decimal places as needed.) b. What is the probability that more than 7 shoppers from this sample felt that regifting was socially acceptable? The probability is. (Type an integer or decimal rounded to four decimal places as needed.) c. What is the probability that fewer than 10 shoppers from this sample felt that regifting was socially acceptable? The probability is (Type an integer or decimal rounded to four decimal places as needed.) d. What are the mean and standard deviation for this distribution?
