You suspect that an unscrupulous employee at a casino has tampered with a die; that is, he is using a loaded die. In order to test your suspicion, you rolled the die in question 200 times and obtained the following frequencies for each of the six possible outcomes of the die: Number Frequency 1 45 2 39 3 35 4 25 27 29 Can you conclude that the die is loaded? Use a=0.05 as the significance level and perform a hypothesis test. Remember to state the null and alternative hypothesis.
