Answer:
0.0069
Step-by-step explanation:
According to the Question,
- Given That, X is a normally distributed random variable with a mean of 22 and a standard deviation of 5. The probability that x is less than 9.7
We have, μ=22 , σ= 5 , P(X<9.7)=Area to the left of 9.7.
Z = (x-μ)/σ
Z = (9.7-22) / 5 ⇒ -2.46
Thus,
- P(X<9.7)=P(Z < -2.46) ⇒ 0.0069 (From z-table)
