Consider the standard 6-sided die (or number cube). If we assume a die is fair, each side should be equally likely. Suppose we roll a die 100 times and observed the results shown below. Is there enough evidence at the 5% level of significance to say that the die is not fair? Frequency 1 2 3 4 5 6 Observed 22 12 17 13 10 26 Expected

Step 1
Null hypothesis: The die is fair, and each side has an equal probability of 1/6. Alternative hypothesis: The die is not fair, and at least one side has a different probability than 1/6. Show more…

A six-sided die is rolled 30 times and the numbers 1 through 6 appear as shown in the following frequency distribution. At the .10 significance level, can we conclude that the die is fair?
Christopher D.
Suppose a fair six-sided die is tossed to see if it fair. We roll the die 300 times and observe the frequency of occurrence of each of the faces. Since the die contains six sides, we expect that the number on each side will occur 50 times. The following frequencies were observed: Face value Occurrence 1 42 2 55 3 38 4 57 5 64 6 44 Conduct a Chi-sq Goodness of Fit test to see if the die should still be considered fair.
Sri K.
The table shows the results of rolling a six-sided die 120 times. $$\begin{array}{|c|c|}\hline \text { Outcome on Die } & \text { Frequency } \\\hline 1 & 27 \\\hline 2 & 20 \\\hline 3 & 22 \\ \hline 4 & 23 \\\hline 5 & 19 \\\hline 6 & 9 \\\hline\end{array}$$ Test the hypothesis that the die is not fair. A fair die should produce equal numbers of each outcome. Use the four-step procedure with a significance level of $0.05$, and state your conclusion clearly.
