Inference & Hypotheses (Lesson 6/6)

Binomial & Poisson Tests

1 / 6

Discussion

A 6-sided die is rolled 40-times, and a 1 is obtained 11 times. Let X be the number of 1s rolled.

(a)

State the distribution of X assuming the die is fair.

Solution:

This is a classic binomial distribution:

X∼B(40,61)
