The mean weekly expenditure for households with this income is E(yx = $2,000) = My-$2,000 $200, and expen- ditures exhibit variance var(ylx = $2,000) = $2,000 = 100. yx (a) Assuming that weekly food expenditures are normally distributed, find the probability that a household with this income spends between $180 and $215 on food in a week. Include a sketch with your solution. (b) Find the probability that a household with this income spends more than $250 on food in a week. Include a sketch with your solution. (c) Find the probability in part (a) if the variance of weekly expenditures is var(ylx = $2,000) = $2,000 = 81. ²2, (d) Find the probability in part (b) if the variance of weekly expenditures is var(ylx = $2,000) = ², -$2,000 81.
