    Answer:

    a)17.92

    b) 16.83 …. 21.17

    Step-by-step explanation:

    ρ→   z

    0.14 = -1.080319341

    -1.080 = (x – 19)/1 = 17.92

    ~~~~~~~~~~~~~~~~~~

    3% / 2 = 1.5%

    1.5% – 98.5%

    ρ→   z

    0.015 = -2.170090378 ….  -2.17 = (x-19) =16.83

    0.985 = 2.170090378  ….   2.17 = (x-19) =21.17
