The poputation proportion for households that spend more than $100 per week on groceries was glven to be 0.17, Let p represent the sample aroportion for a group of 900 households. To be within 0.02 of the population proportion of 0.17 gives a range of houly wages between 0.170.02= and 0.17+0.02= Therefore, the desired probability that a sample proportion of 900 hausehalas is wethin 0.02 of the population praporten is
