Answer:
Hence,
a) The probability that the sample average would be less than 90 pounds is 0.0210.
b) The probability that the sample average would be between 98 and 105 pounds is 0.5045.
c) The probability that the sample average would be less than 112 pounds is 0.9935.
d) The probability that the sample average would be between 93 and 96 pounds is 0.1341.
Step-by-step explanation:
a)
= P(Z < -2.03) = 0.0210
b )
= P(-0.39 < Z < 1.05) = 0.5045
c )
= P(Z < 2.49) = 0.9935
d )
= P( -1.42 < Z < -0.8 )
= 0.2119 - 0.0778 = 0.1341
