A fair die is rolled ten times and each time the face up is recorded. Calculate the probability that exactly four numbers greater than 4 have been recorded. (Answer must be rounded off to the nearest thousandth) What is the expected number of times a number less than 5 will be recorded? (Answer must be rounded off to the nearest thousandth)

In an experiment in which a die was thrown110 times, the number of times each face came up was as follows: Face 1 Face 2 Face 3 Face 4 Face 5 Face 6 13 24 16 11 13 33 Calculate the goodness-of-fit test statistic for a test of the fairness of the die, using the formula . State, giving your reasons, how many degrees of freedom the test statistic has, check it for significance at the 5% level and state...

Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion. A person drilled a hole in a die and filled it with a lead weight, then proceeded to roll it 200 times. Here are the observed frequencies for the outcomes of 1, 2, 3, 4, 5, and 6, respectively: 2828, 46, 37, 29, 32. Use a 0.025 significance level to test the claim that the outcomes are not equally likely. Does it appear...

Suppose you have a six sided die. One face is printed with the number 1. Two faces are printed with the number 2. Three faces are printed with the number 3. You also have 3 coins: C_1, C_2, and C_3. C_1 will land Heads with probability 1/3. C_2 will land Heads with probability 1/5. C_3 will land Heads with probability 1/4. You roll the die. If the die lands with a 1 face up, flip coin C_1 If the die...
