1. Determine whether the given value is a statistic or a parameter: The average (mean) weight

of all newborns in a hospital over a month is 7.5 pounds.

• A. Statistic

• B. Parameter
nn




nn Answer: B nn




Rationale: Since it refers to the entire population of newborns in the hospital, it is a parameter.

found that 60% were satisfied with their healthcare.

• A. Statistic

nn Answer: A nn




Rationale: The value is based on a sample, making it a statistic.

this?

Rationale: The number of visits is discrete data because it represents countable whole numbers.

• A. Nominal

• C. Interval

• D. Ratio

differences between values.

nn Answer: C
nn




Rationale: Temperature in Celsius is interval data because it has no true zero, but the differences

between values are meaningful.

measurement is this?

• A. Nominalnn




• B. Ordinalnn
