Transcribed Image Text:Ojai is a weather station in the state of California and Duxbury is a weather station in the state of Massachusetts. On one
summer day, the noontime temperatures recorded among weather stations in California had a population mean of 27.7°
Celsius and a standard deviation of 4.8° Celsius. On that same day, the noontime temperatures among weather stations in
Massachusetts had a population mean of 37.1° Celsius and a standard deviation of 6.2° Celsius. On the summer day, each
state's distribution of noontime temperatures among its weather stations was clearly skewed (not approximately
symmetric),
At the Ojai weather station, the noontime temperature on the summer day was 17° Celsius, and the noontime temperature
at Duxbury was 20° Celsius.
(a) Find the z-scores of Ojai's noontime temperature on the summer day as a weather
station in California and Duxbury's noontime temperature on the summer day as a
weather station in Massachusetts. Round your answers to two decimal places.
z-score of Ojai's noontime temperature:
z-score of Duxbury's noontime temperature:
(b) Relative to its population, which weather station had the higher noontime temperature?
Choose the best answer based on the z-scores of the two noontime temperatures.
O Ojai
O Duxbury
It is unclear which weather station had the higher noontime temperature relative to its
population.
