(b) What is the probability that the sample proportion will be within 10.02 of the population proportion? The population proportion for households that spend more than $100 per week on groceries was given to be 0.17. Let 5 represent the sample proportion for a group of 700 households. To be within 0.02 of the population proportion of 0.17 gives a range of hourly wages between 0.17 0.02 = 0.15 v and 0.17 + 0.02 = 0.19 q . Therefore, the desired probability that a sample proportion of 700 households is within 0.02 of the population proportion is P( -0.41 x s ,5 s 0.41 x ). Submit Skip (you cannot come back)
