A Food Marketing Institute found that 52% of households spend more than $125 a week on groceries. Assume the population proportion is 0.52 and a simple random sample of 119 households is selected from the population. What is the probability that the sample proportion of households spending more than $125 a week is more than than 0.48? Note: You should carefully round any z-values you calculate to 4 decimal places to match wamap's approach and calculations.
