The Food Marketing Institute shows that 15% of households spend more than $100 per week on groceries. Assume that the population proportion is 0.15. A random sample of 566 households is selected from the population; therefore, the standard error of the sample proportion is 0.015. What is the probability that the sample proportion will be between 0.12 and 0.165? O a. 0.8641 Ob0.8186 O c 0.8413 O d. 0.0228
