Crunchy Corn Chips are packaged in bags labeled "net weight 10 ounces
The amount of corn chips dispensed into a 13-ounce bag by the dispensing machine has been identified as possessing a normal distribution with a mean of 13.5 ounces and a standard deviation of 0.3 ounce. Suppose 40 bags of chips were randomly selected from this dispensing machine. Find the probability that the sample mean weight of these 40 bags exceeded 13.6 ounces.
A factory knows that the weight of bags of chips they make will vary slightly. If the mean weight of a bag of chips is 16 ounces with a standard deviation of 0.5 ounces, what is the weight of a bag of chips at the 22.5th\rd\ nd percentile at the factory?

Bags of a certain brand of tortilla chips claim to have a net weight of 14 ounces. Net weights actually vary slightly from bag to bag. Assume net weights are Normally distributed. A representative of a consumer advocate group wishes to see if there is any evidence that the mean net weight is less than advertised and so intends to test the hypotheses H0: μ = 14 versus Ha: μ < 14. To do this, he selects 16 bags of...
