Many consumers pay careful attention to stated nutritional contents on pack- aged foods when making purchases, so it is important that the information on packages be accurate. Suppose that a random sample of n = 12 frozen dinners of a certain type was selected and the calorie content of each one was determined. Below are the resulting observations. 255 244 239 242 265 245 259 248 225 226 251 233 The manufacturer claims that the mean calorie content for this particular type of frozen dinner is 240. Carry out a formal test of the hypothesis.
