Question

For a normal distribution with mean 0 and standard deviation 1, which of the following Python lines outputs the probability?

1) scipy.stats.norm.pdf(0, 0, 1)
2) scipy.stats.norm.cdf(0, 0, 1)
3) scipy.stats.norm.ppf(0, 0, 1)
4) scipy.stats.norm.rvs(0, 0, 1)

Answer 1

The correct Python line to output the probability for a normal distribution with mean 0 and standard deviation 1 is scipy.stats.norm.cdf(0, 0, 1).

Step-by-step explanation:

The correct Python line to output the probability for a normal distribution with mean 0 and standard deviation 1 is scipy.stats.norm.cdf(0, 0, 1). This line calculates the cumulative distribution function (CDF) of the normal distribution, which gives the probability of a random variable being less than or equal to a certain value. In this case, the value is 0. By using the CDF function, we can find the probability of a value being within a specific range.
