A Food Marketing Institute found that 25% of households spend more than $125 a week on groceries. Assume the population proportion is 0.25 and a simple random sample of 316 households is selected from the population. What is the probability that the sample proportion of households spending more than $125 a week is less than 0.23? There is a probability that the sample proportion of households spending more than $125 a week is less than 0.23. Round the answer to 4 decimal places.
