16. The average income of 15 randomly selected families who reside in cities is $62,456, with a standard deviation is $9652. The average income of 11 randomly selected families who reside in rural areas in the Midwest is $60,213, with a standard deviation of $2009. Assume the population variances are not equal. At a = 0.10, is there sufficient evidence to support the claim that families who live in cities have a higher income than those who live in rural areas? Show all steps of the hypothesis test you conduct.
