Problem 67Multiple Choice

A researcher tests whether the population standard deviation of annual household electricity usage differs from the historical value of $sigma sub 0 equals 300$ kilowatt-hours ( $kWh$ ). The test returns a $p$ - value of $0.12$ . Which interpretation is most accurate?

There is strong evidence that the population standard deviation differs from $300 kWh$

There is strong evidence that the population standard deviation is equal to $300 kWh$

There is insufficient evidence to conclude that the population standard deviation differs from $300 kWh$

The sample standard deviation is greater than $300 kWh$
