A random sample of 193 people ages 16 to 19 were taken from the island of
Oahu, Hawaii, and 19 were found to be high school dropouts. Another random
sample of 159 people ages 16 to 19 were taken from Sweetwater County,
Wyoming, and 13 were found to be high school dropouts. Do these data values
indicate the population proportion of high school dropouts on Oahu is more than
that of Sweetwater County? Use a 5% level of significance to test the claim.
