Final answer:
The data set of body temperatures of students at the local university is expected to be normally distributed, while the data set of exact weights of DVDs is not expected to be normally distributed.
Step-by-step explanation:
To decide which of the given data sets you would expect to be normally distributed, consider the characteristics of each set.a) The exact weights of a random sample of DVDs from the same manufacturer: The weights of DVDs are likely to vary slightly due to manufacturing processes, transportation, and packaging. Therefore, this data set is not expected to be normally distributed.
b) The body temperatures of the students at the local university: Body temperatures in a healthy adult population are known to follow a normal distribution. Therefore, this data set is expected to be normally distributed.
