select the correct answer. which statement is true? a. point estimates are used to make inferences about population parameters. b. when we use the population mean and proportion to summarize information about the entire population, we call them point estimates. c. the population mean and proportion are always equal to their corresponding point estimates. d. the sample mean and sample proportion of a population are called population parameters.
Answer

Point - estimates are single - value estimates of population parameters. They are used to make inferences about population parameters. Population mean and proportion are parameters, sample mean and proportion are statistics. Point estimates are based on sample data and are not always equal to population parameters.
Answer:
A. Point estimates are used to make inferences about population parameters.
