In a marketing campaign to increase lagging sales of their oatmeal raisin cookies, the Quaker Oats Company announced the "Raisin" the Roof Challenge, claiming that 30-ounce packages of their oatmeal raisin cookies contained on average more than 1200 raisins. Dedicated statistics students at Princeton University (no kidding) purchased randomly selected packages of Quaker Oats oatmeal raisin cookies and counted the number of raisins in each package. Some of their data are shown below:

1219 1214 1087 1200 1419 1121 1325 1345

1244 1258 1356 1132 1191 1270 1295 1135

The shape of the distribution of the number of raisins per package is approximately mound-shaped with very little skewness and no outliers.

We will use the above data to perform a hypothesis test to evaluate the Quaker Oats Company's claim.

Question 1. The null hypothesis is H0: μ = 1200, where μ is the mean number of raisins per 30-ounce package. Select the alternative hypothesis from the choices below Note: 2 submissions ONLY.
