Question
You want to see if a card dealer is favoring one suit over another. You observe the dealer pick a card, put it back in the deck, shuffle, and then repeat the process 288 times. The results are displayed on the table below. Use an α = 0.10 significance level.
- Complete the rest of the table by filling in the expected frequencies:
Outcome | Frecuency |
Expected Frecuency |
Spades | 48 |
|
Hearts | 72 | |
Diamonds | 87 | |
Clubs | 81 |

- What is the correct statistical test to use?
Select an answer:( 1 ANSWER) Independence:, Goodness-of-Fit; Homogeneity; Paired t-test. - What are the null and alternative hypotheses?
H0:- The suits and cards are dependent.
- The distribution of suits is uniform.
- The distribution of suits is not uniform.
- The suits and cards are independent.
- H1:
- The distribution of suits is uniform.
- The suits and cards are dependent.
- The suits and cards are independent.
- The distribution of suits is not uniform.
- The degrees of freedom = ____
- The test-statistic for this data = ________(Please show your answer to three decimal places.)
- The p-value for this sample =________ (Please show your answer to four decimal places.)
- The p-value is _______ α
- Based on this, we should Select an answer_______

To do this, suppose you perform an experiment in which you roll an eight-sided die two times (or equivalently, roll two eight-sided dice one time) and calculate the mean of your sample. Remember that your population is the numbers 1, 2, 3, 4, 5, 6, 7, and 8. The true mean (µ) of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 is , and the true standard deviation (o) is The number of possible different samples (each of size n = 2) is the number of possibilities on the first roll (8) times the number of possibilities on the second roll (also 8), or 8(8) = 64. If you collected all of these possible samples, the mean of your sampling distribution of means (µM) would equal and the standard deviation of your sampling distribution of means (that is, the standard error or ɑm) would be The following chart…arrow_forwardThe top 16 winning scores for NFL games are listed below.
