Question

According to the attached graph of normal distribution, we can say that the probability of this distribution is:

a) P(z<1,48)

b) P(z<0,39)

c) P(z<0,39) - P(z<1,48)

d) P(z<1,48) - P(z<0,39)

I think the correct answer is the d option, is it correct?

u = 186
o = 35,8
200 <x < 239
75
200 239
300

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
