A Federal funding program is available to low income neighborhoods. To qualify for the funding a neighborhood must have a mean household income of less then \$15,000 per year. Neighborhoods with mean household income of \$15,000 or more do not qualify. Funding decisions are based on a sample of residents in the neighborhood. A hypothesis test with a .02 level of significance is conducted. If the funding guidelines call for a maximum probability of .05 of not funding neighborhood with a mean annual household income of \$14,000, what sample size should be used in the funding decision study?
