# 2.2 A household has weekly income of \$2,000. The mean weekly expenditure for households

Question: 2.2 A household has weekly income of \$2,000. 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

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. error: Content is protected !!
