Final answer:
The probability of all values of x that are more extreme than 2.5 is 0.24.
Step-by-step explanation:
In this question, we are given that the left tail probability at x = 2.5 is 0.76. To find the probability of all values of x that are more extreme than 2.5, we can subtract the left tail probability from 1.
So, the probability of all values of x that are more extreme than 2.5 is:
1 - 0.76 = 0.24.
Therefore, the probability is 0.24.
