    The study conducted by the Canadian Council on Foreign Affairs also asked the respondents questions about
    their income and found that the household income can be modeled as a Gaussian distribution with mean $73
    200 and standard deviation $33 200.

    4.) The CCFA is also fundraising to support their global access to information projects and hopes
    to persuade 900 households to donate 0.5% of their household income to the CCFA. Assuming that each
    of the 900 homes in the sample would indeed donate exactly 0.5% of their income, what is the
    probability that the total charitable revenue so collected would exceed $400K?

    Does anyone know how would i would be able to find the mean?
