If X is a normally distributed variable with u=16 and standard deviation o=4, then what is the probability P(X<26)?
Note: Use the standard normal distribution table below, where Z has mean u=0 and standard deviation o=1
N
P(0 < Z < z)
1
0.3413
1.5
0.4332
2
0.4772
2.5
0.4938​

Answer 1

Step-by-step explanation:

P( x<26)

P(Z<26-16/4)

P(Z<2.5)

0.4938+ 0.5

Ans : 0.9938
