Suppose an airline decides to conduct a survey of its customers to determine their opinion of a proposed one-bag limit.
 
  The plan calls for a random sample of customers on different flights to be given a short written survey to complete during the flight. One key question on the survey will be: Do you approve of limiting the number of carry-on bags to a maximum of one bag? Airline managers expect that only about 15 will say yes. Based on this assumption, what size sample should the airline take if it wants to develop a 95 confidence interval estimate for the population proportion who will say yes with a margin of error of 0.02?A) 1151
  B) 1341
  C) 1512
  D) 1225

Question 2

The makers of a particular type of candy have stated that 75 percent of their sacks of candy will contain 6 ounces or more of candy. A consumer group that studies such claims recently selected a random sample of 100 sacks of this candy.
 
  Of these, 70 sacks actually contained 6 ounces or more. The probability that 70 or fewer sacks would contain 6 ounces or less is approximately 0.1251. Indicate whether the statement is true or false
