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 256 times. The results are displayed in the table below. Use an αα = 0.10 significance level.
- Complete the rest of the table by filling in the expected frequencies:
Outcome Frequency Expected Frequency Spades 49 Hearts 75 Diamonds 69 Clubs 63 - What is the correct statistical test to use?
- What are the null and alternative hypotheses?
H0:- The distribution of suits is uniform.
- The suits and cards are dependent.
- The distribution of suits is not uniform.
- The suits and cards are independent.
H1:- The suits and cards are independent.
- The suits and cards are dependent.
- The distribution of suits is not uniform.
- The distribution of suits is 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 Greater Than or less than αα (Choose one)
- Based on this, we should
- Thus, the final conclusion is...
- There is insufficient evidence to conclude that suits and cards are dependent.
- There is sufficient evidence to conclude that the distribution of suits is uniform.
- There is sufficient evidence to conclude that suits and cards are dependent.
- There is insufficient evidence to conclude that the distribution of suits is not uniform.
- There is sufficient evidence to conclude that the distribution of suits is not uniform.

- Textbook question for practise - A behavioural psychologist has developed a cognitive-behavioural therapy (CBT) technique modified from classic systematic desensitization to reduce her patients’ phobia of spiders. She decides to test the effectiveness of her new therapy approach by selecting ten patients at random to undergo the treatment for 3 months. The patients were asked to rate how much fear they feel/experience when in the presence of a spider/spiders using a scale from 0 (no fear at all) to 100 (extreme panic and fear). They were tested before and after the therapy. The ratings for each patient are as follows: For this question, be sure to do the following: ▪ State the statistical hypotheses (using the appropriate notation). ▪ Indicate whether the research hypothesis is non-directional or directional (and how you know). ▪ Set the decision rules, which will include: o State alpha - 0.05% o Compute the degrees of freedom o Providing the critical value for the test statistic…arrow_forwardUse the dataset of GPAs below to calculate the tail probability of a GPA of 1.3.
