Thank you for the solution. Can you please explain me the hypothesis that were formed for this problem. My doubt is if the statistical value is more than the critical value we reject the null hypothesis and conclude that there is an association. Kindly clarify

[@subject360]

If calculated value > critical value (table value), null hypothesis is rejected and alternate hypothesis is accepted

Mam, I have one doubt, Exactly 8:12 you are saying about row and column value as 6 but how it comes "x square 2 0.05". Based on tabke you have mentioned it 12.6, my question how could you use 0.05.Please help me to understand.

[@subject360]

Since no significance is mentioned in question, by default we consider the significance to be 5% and hence it's 0.05. I have explained as how to find value from table at the beginning of the video at 2:11. Hope this clarifies your doubt

A brand manager is concerned that her brand's share may be unevenly distributed throughout the country. In a survey in which the country was divided into 4 geographic regions, a random sampling of 100 consumers in each region was surveyed with the following results. In the North East region, 40 purchased the brand and the rest did not purchase. In the North West region, 55 purchased the brand and the rest did not purchase. In the South East region, 45 purchased the brand and the rest did not purchase. In the South West region, 50 purchased the brand and the rest did not purchase. At a = 0.05, Use Chi Square test to check whether the brand share is the same across the four regions. Akka this sum la we need to create table like purchased and not purchased with each region?
