The Food Marketing Institute shows that17% of householdsspend more than $100 per week on groceries. Assume that the population proportion isP = .17 and a sample of 600 householdswill be selected from thepopulation.

Answer the following questions. The requirements to use the normal distribution,are satisfied.

1.Calculate the standard error oftheproportion of households spending more than $100 per week on groceries (to 4decimals).

2.What is the probability that the sample proportion will be within +/- .03of the population proportion (to 4 decimals)?

Find the values of z-scores first.
