A farm produces thousands of 1-pound packages of cheese every month. Administrative specifications allow for no more than 3 percent of the 1-pound packages to be underweight. To investigate compliance with the specifications, the farm’s manager selected a random sample of 500 packages of cheese produced in one month and found 20 packages, or 4 percent, to be underweight. Assuming all conditions for inference are met, do the data provide convincing statistical evidence at the significance level of that more than 3 percent of all the packages of cheese produced in one week are underweight?

14) Mаny peоple believe thаt they cаn tell the difference between Cоke and Pepsi. Other peоple say that the two brands can't be distinguished. To test this, a random sample of 20 adults was selected to participate in a test. After being blindfolded, each person was given a small taste of either Coke or Pepsi and asked to indicate which brand soft drink it was. If people really can't tell the difference, the expected number of correct identifications in the sample would be:
