QUESTION 2
ILLUSTRATE OR DRAW THE GRAPH THAT SHOWS THE REJECTION AND NON-REJECTION REGION.
A random sample of n_(1)=16 communities in western Kansas for people under 25 years of age and of
n_(2)=14 regions in western Kansas gave the following information for people over 50 years old.
Data(Rate of hay fever per1000 population):
ar{x} _(1)~~109.50,s_(1)~~15.41,ar{x} _(2)~~99.36, and s_(2)~~11.57.
Assume that the hay fever rate in each group has an approximately normal distribution. Do the data
indicate that the age group over 50 has a lower rate of hay fever? Use alpha =0.05.
2. A random sample of n= 16 communities in western Kansas for people under 25 years of age and of n2 = 14 regions in western Kansas gave the following information for people over 50 years old Data(Rate of hay fever per1000 population):
x~109.50, s,~15.41, x ~99.36,and s,~11.57.
Assume that the hay fever rate in each group has an approximately normal distribution. Do the data indicate that the age group over 50 has a lower rate of hay fever? Use a = 0.05.
