SciPy - Statistical Functions (scipy.stats) Basics

Anorm.cdf(4, loc=5, scale=1) + norm.cdf(6, loc=5, scale=1)

Bnorm.cdf(6, loc=5, scale=1) - norm.cdf(4, loc=5, scale=1)

Cnorm.sf(4, loc=5, scale=1) - norm.sf(6, loc=5, scale=1)

Dnorm.pdf(6, loc=5, scale=1) - norm.pdf(4, loc=5, scale=1)

Step-by-Step Solution

Solution:

Step 1: Understand probability between two values
Probability between a and b is CDF(b) - CDF(a).
Step 2: Apply correct parameters
Use loc=5, scale=1 for both CDF calls at 6 and 4.
Final Answer:
norm.cdf(6, loc=5, scale=1) - norm.cdf(4, loc=5, scale=1) -> Option B
Quick Check:
Probability between = CDF(b) - CDF(a) [OK]

Quick Trick: Subtract CDFs to get probability between two points [OK]
