A. Statistical Intuitions in Mental Health
A
**Question 1: ** (#Probability, #CompProgram Design, #Visualizations)
We are going to work with a dataset that was collected on mental health issues. In total, 824 individuals
(teenagers, college students, housewives, businesses professionals, and other groups) completed the survey.
Their data provides valuable insights into the prevalence, and factors associated with, mental health issues in
different groups.
Using the sample dataset from the CSV file you generated answer the following questions:
Question 1a. Is each of these two variables independent of being female? Explain your reasoning. Make sure to
include a two-way table for each of these two variables with gender, and show all your calculations to support
your answers.
**Question 1b. **Is there a relationship between the two variables returned by the code? Explain your reasoning.
Make sure you include a two-way table, a stacked bar graph, and all your probability calculations in your answer. endent of being female? Explain your reasoning. Make sure to

**Question 1b. **Is there a relationship between the two variables returned by the code? Explain your reasoning.
Make sure you include a two-way table, a stacked bar graph, and all your probability calculations in your answer.
*Question 1c. **Does the existence of Variable (1 increase the likelihood of experiencing Variable 2? If so, by how
much? Explain your reasoning. Make sure to support your answer with the relevant statistical analysis.
**Question 1d. **Look back at your answers to Questions 1a-c. Now use what you learned to answer the following
question: Imagine ZU wanted to use the insights from this research to improve its mental health support program.
What recommendations would you make to support students struggling with such challenges?
B. Statistical Intuition in Store Ratings
**Question 2: ** (#Distributions, #Probability)
Imagine you are the manager of an Electronic store in Dubai mall. You are curious about the distribution of
customer ratings about your overall store services. So you ask random customers who visit the store to complete a
short survey, recording variables such as their age group, and overall experience rating. customer ratings

Question 2a. Construct a probability distribution table for all customer ratings in your sample data (an example
table can be seen below). Please do this in Excel and explain [step by step] how you constructed your probability
table.

Question 2b. What is the probability that a randomly selected customer will have a rating of AT MOST 3?
Question 2c. Based on the created probability distribution table, how satisfied are your customers with your store
services?
Question 2d. Find the expected rating of your store. Show your work and interpret your answer in context.
Question 2e. Interpret the Standard Deviation in context. What rating is considered unusual. Explain.
Question 2f. Identify any trends or differences in customer satisfaction levels (and variability) among the different
age groups.
Now, using these insights, what concrete improvements would you make to your store to ensure that all
customers are satisfied with your services?
