Explanation:

• For Question 9: A confidence interval is constructed to estimate an unknown population parameter. We hope the unknown parameter lies within the confidence - interval. The margin of error determines the width of the interval, the statistic is used to calculate the interval, and the confidence level is the probability that the interval contains the parameter.
• For Question 10: Statistical inference is the process of drawing conclusions about a population based on information in a sample. Selecting data from a population is sampling. Drawing conclusions about a sample based on its own measurements is descriptive statistics in part, not inference. Inference is about the population from the sample.

Answer:

Question 9: the unknown parameter
Question 10: Drawing conclusions about a population based on information in a sample
