A random sample of 5 backpacks will be weight, in pounds, of each backpack will be recorded. For samples of size 5, which of the following is the best interpretation of Pl (a > 22) 0.05?a. The probability that each of the 5 backpacks selected will have a weight above 22 pounds is approximately 0.05.b. The probability that each of the 5 backpacks selected will have a weight above 19.7 pounds is approximately 0.05c. The probability that the population mean is greater than 22 pounds is approximately 0.05.d. For all samples of size 5, approximately 5% of the sample will have a probability greater than 22 pounds,e. For all samples of size 5, the probability that the sample mean will be greater than 22 pounds is approximately 0.05.
