Answer: 0.819
Step-by-step explanation:
Given: X is a normally distributed random variable with mean 95 and standard deviation 3.
Then, the probability that X is between 89 and 98 will be:
![P(89](https://tex.z-dn.net/?f=P%2889%3CX%3C95%29%3DP%28%5Cdfrac%7B89-95%7D%7B3%7D%3C%5Cdfrac%7BX-mean%7D%7Bstandard%5C%20deviation%7D%3C%5Cdfrac%7B98-95%7D%7B3%7D%29%5C%5C%5C%5C%3DP%28-2%3CZ%3C1%29%5C%20%5C%20%5C%20%5BZ%3D%5Cdfrac%7BX-mean%7D%7Bstandard%5C%20deviation%7D%5D%5C%5C%5C%5C%20%3DP%28Z%3C1%29-%281-P%28Z%3C2%29%29%5C%5C%5C%5C%3D%200.8413-%20%281-0.9772%29%5C%20%5C%20%5C%20%5B%5Ctext%7BBy%20p-value%20table%7D%5D%5C%5C%5C%5C%3D%200.8185%5Capprox0.819)
Hence, the required probability = 0.819
