Suppose we want to test to see if a die is “fair”.
When the die is tossed 240 times the following results are obtained.
Value: 1 2 3 4 5 6
observed frequency: 36 47 35 42 44 36
a) find the expected frequencies if the die is fair.
b) calculate the chi-squared statistics.
c) find the 5% critical value
d) test the hypothesis that the die is fair
