A random sample of 663 teens who said they did not typically eat fast food reported an average daily calorie intake of 2258, with standard deviation 1519. A random sample of 413 teens who said they did typically eat fast food reported an average daily calorie intake of 2637, with standard deviation 1138. The two populations are not terribly skewed. Based on the above description, which of the following conditions are met for conducting a hypothesis test for the equality of two means? Choose one or more that apply.
