Challenge 1 A survey on Internet usage was conducted among a group of 200 students in the school cafeteria. It was found that 100 students spend at least two hours online every day. Which of these is an example of descriptive statistics? a.) 50% of the students surveyed spend at least two hours online each day. b.) 50% of the students in the cafeteria spend at least two hours online each day. c.) 50% of the students in a class spend at least two hours online each day. d.) 50% of the students in the school spend at least two hours online each day. Recall that descriptive statistics simply notes what we find in some samples. Since we are simply noting how many people in the survey spend at least two hours on the Internet, this is a descriptive statistic about the survey.

A company packed 8 dark chocolates in a box of 32 assorted chocolates. Which of these does NOT represent inferential statistics? a.) 25% of the chocolates manufactured in a factory are dark chocolates. b.) 25% of the chocolates packed in a day are dark chocolates. c.) 25% of the chocolates in a box are dark chocolates. d.) 25% of the chocolates manufactured in a batch are dark chocolates.  Recall that inferential statistics allows us to make inferences about a population based on some sample value. So noting that there are 25% of chocolates in a box is an example of a descriptive statistic. If we were to use that information to make broader inference, then it would be inferential.
