  • You are employed as a statistician for a company
    that makes household products, which are sold by
    part-time salespersons who work during their
    spare time. The company has four salespersons
    employed in a small town. Let us denote these
    salespersons by A, B, C, and D. The sales
    records (in dollars) for the past 6 weeks for
    these four salespersons are shown in the table

    the manager in a small town in the lake district
    of a Midwestern state enjoys a robust tourist
    season during the summer months, but has only a
    small population of residents during the off
    season. The Littletown Café adjusts the levels of
    staff according to the time of year, to coincide
    with the number of guests, with the tourist
    season typically starting around Memorial Day
    each year. One wait staff employee can serve 50
    guests. When a bus staff employee is added, the
    pair can serve 75 guests. At 76 guests, the café
    adds a second wait staff employee, for a total of
    2 waiters and one busser. Analysis of guest
    numbers can support future decisions about
    scheduling wait staff, dishwashers, and bus staff
    for the café.

    was asked to rate the appeal of the phrase Not
    sweet like wine coolers, not filling like beer,

             You work in marketing for a company
    that produces work boots. Quality control has
    sent you a memo detailing the length of time
    before the boots wear out under heavy use. They
    find that the boots wear out in an average of 208
    days, but the exact amount of time varies,
    following a normal distribution with a standard
    deviation of 14 days. For an upcoming ad
    campaign, you need to know the percent of the
    pairs that last longer than six months-that is,
    180 days. Use the empirical rule to approximate
    this percent.Question 2      For any normally
    distributed random variable with mean µ and
    standard deviation s, the percent of the
    observations that fall between µ-2s  and µ2s  is
    closest to _______.         Question 3

    correct?Question 4                 What does
    it mean when we say that the tails of the normal
    curve are asymptotic to the x axis?Question
