Which of the following is the correct syntax to calculate the CDF of a standard normal distribution at value 1.5 using scipy?
Which of the following is the correct syntax to calculate the CDF of a standard normal distribution at value 1.5 using scipy?
easy📝 Syntax Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Recognize the correct import and function for CDF
norm.cdf(x) computes the cumulative distribution function for normal.Step 2: Check syntax correctness
from scipy.stats import norm; norm.cdf(1.5) imports norm and calls cdf correctly; others use wrong functions or methods.Final Answer:
from scipy.stats import norm; norm.cdf(1.5) -> Option DQuick Check:
Correct import and .cdf() usage [OK]
Quick Trick: Import norm and use .cdf(x) for cumulative probability [OK]
Common Mistakes:
MISTAKES- Using pdf() instead of cdf()
- Using pmf() for continuous distribution
- Incorrect import statements
