Question 6
(The following comprehension is purely imaginary) The BA team is known for their clumsy QP setting. Hence, after every quiz the enrolled learners always raise concerns. These concerns can be grouped into five categories: “Category-1: Not a valid concern- No Correction”, “Category-2: Valid Concern-Minor Correction”, “Category-3: Valid Concern-Major Corrections”, “Catgeory-4: Valid Concern-Open Marks” and “Catgeory-5: Those who claim marks for their misconception”. From the past six terms (Jan-20 to Sep-21), data on the number of requests in each category is captured and presented in Table-2 below. Given this information, answer the given sub-questions
Table-2: Category-Term Count Data
If the aim is to check if the counts of observations in each category is independent across terms, then what is the degrees of freedom for the test-statistic? (Note: Enter your answer in decimals rounded to two decimal places. For example, if your answer is “0.245”, enter it as “0.25”)
