    c. What are the first and third quartiles?

    Explanation:

    Company Advertising expense (in $ billion)

    Procter and Gamble 5.00

    American Express 2.19

    Comcast 3.08

    General Motors 2.15

    AT&T 2.91

    Toyota 2.09

    Ford 2.56

    Fiat Chrysler 1.97

    mean $2.55 billion

    median is between $2.19 and $2.34 ⇒ ($2.19 + $2.34) / 2 = $2.265

    first quartile = ($1.88 + $1.96 + $1.97 + $2.09 + $2.15 + $2.19) / 6 = $12.24 / 6 = $2.04

    third quartile = ($2.34 + $2.44 + $2.56 + $2.91 + $3.08 + $5) / 6 = $18.33 / 6 = $3.055
