A researcher wants to test whether a 6 sided die is not fair. He rolled the die 2400 times and got the following result:
|
one dot |
two dots |
three dots |
four dots |
five dots |
six dots |
|
530 |
430 |
730 |
439 |
150 |
121 |
Conduct a Chi Square Goodness-of-Fit analysis to test that the die is not fair. Use the significance level of 0.05
Homework Answers
Answer #1
Under null hypothesis;H0: the die is fair that means probability of getting any number is 1/6
Vs
Alternative hypothesis;H1: the die is not fair.
Under the null hypothesis , expected no. Of dots obtained (ek)=2400/6=400

A six-sided fair die is rolled six times independently. If side
i is observed on the ith roll, it is called a match on the ith
trial, i = 1, 2, 3, 4, 5, 6. Find the probabilities that
(a) all six trials result in matches,
(b) at least one match occurs in these six trials,
(c) exactly two matches occur in these six trials.
