"Use sample mean and sample proportion to estimate population mean and population proportion." "Interpret margin of error. Understand that a larger sample size generally leads to a smaller margin of error."

"Use sample mean and sample proportion to estimate population mean and population proportion."
"Interpret margin of error. Understand that a larger sample size generally leads to a smaller margin of error."

What you'll learn

Estimate a population mean or proportion from the mean or proportion of a random sample, and interpret the estimate's margin of error as a range of plausible values for the population value
Use a sample proportion to estimate the number of members of a population that have a characteristic
Decide whether a statement about a population is supported by an estimate and its margin of error
Predict how the margin of error changes when the sample size changes
