A Random Sample of Heights (In Feet) of Active Volcanoes $2385.9$

Multiple Choice

A random sample of heights (in feet) of active volcanoes in North America, outside of Alaska , is shown. Is there sufficient evidence that the standard deviation in heights of volcanoes outside of Alaska is less than the standard deviation in heights of Alaskan volcanoes, which is $2385.9$ feet? Use $\alpha = 0.05$ .

A) No. There is not enough evidence to support the claim that the standard deviation is less than 2385.9 feet.
B) Yes. There enough evidence to support the claim that the standard deviation is less than 2385.9 feet.
C) There is not enough information to draw a conclusion.
