Let X be normally distributed with mean ? = 104 and standard deviation ? = 33. Use Table 1.
a.Find P(X ? 100). (Round “z” value to 2 decimal places and final answer to 4 decimal places.)
P(X ? 100)
b.Find P(95 ? X ? 110). (Round “z” value to 2 decimal places and final answer to 4 decimal places.)
P(95 ? X ? 110)
c.Find x such that P(X ? x) = 0.330. (Round “z” value and final answer to 2 decimal places.)
x
d.Find x such that P(X > x) = 0.820. (Round “z” value and final answer to 2 decimal places.)
x
