Please help thank you!
ser-zykov [4K]

Answer:

a) 91.4%

b) 37.6%

c) 26.8%

Step-by-step explanation:

For each of these, we'll get a z-score, then use our calculators to find the area using normalcdf (on TI-84, 2nd->VARS->2)

a)  z = (9-6.4) / 1.9 = 1.368

    normalcdf(-999,1.368) = .914 = 91.4%

b) z = (7-6.4) / 1.9 = .316

   normalcdf(.316,999) = .376 = 37.6%

c) normalcdf(.316,1.368) = .268 = 26.8%
