A consumer group claims that Chuck’s Chips' snack-pack size has an average weight below 1.75 ounces, which is the weight labeled on the bags. In an attempt to substantiate this claim, a researcher from the consumer group randomly selects 36 bags and finds that the average weight is 1.73 ounces. She also calculates a standard deviation ( s s ) to be 0.33 ounces. Assume the random variable, Chuck’s Chips' snack-pack size (denoted by X), is normally distributed.
