A Food Marketing Institute found that 41% of households spend more than $125 a week on groceries. Assume the population proportion is 0.41 and a simple random sample of 176 households is selected from the population. What is the probability that the sample proportion of households spending more than $125 a week is between 0.3 and 0.43? Note: You should carefully round any z-values you calculate to 4 decimal places to match wamap's approach and calculations.
