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. Question 13 Not yet answered Points out of 1.00 Flag question Question text Specify the null and alternative hypotheses. Select one:

a. H(0): μ ≥ 1.75 Versus H(a): μ < 1.75
