Grossmont College Students Probability Statistics Question

Question 2 – Two-Way Tables

Prompt

1. Use StatCrunch to produce a two-way contingency table as we did in Unit 3 (Module 8). Use the row variable “gender” and column variable “class”.
   • Copy the table in your StatCrunch output window and paste it in your response.
   • After you paste the content of your StatCrunch output window into your discussion post, keep the table titled Contingency table results, and delete the Chi-Square results.
2. Analyze the data in your two-way table by finding appropriate percentages for each bullet point below. Write each conditional percentage as a ratio (e.g. 25 out of 40) and as a percentage (e.g. 25/40 = 62.5%).
   • What percentage of students are females?
   • What percentage of students are males and seniors?
   • What percentage of female students are sophomores?
   • What percentage of first-year students are male?
