Question

We want to test if the variables X space and Y space are independent, for this, a sample of size n is selected and the data are arranged in a table of 4 rows by 6 columns and we obtain a chi subscript c superscript 2 equal 26.321, we can conclude that:

Note: You must use the table in the guide text.

Question 1 options:

a) At a 1% significance level, variables X and Y are independent but not at 5%.

b) At a significance level of 5%, variables X and Y are independent but not at 1%.

c)At 1% significance level, variables X and Y are dependent and also at 5%.

d)At 1% significance level, variables X and Y are independent and also at 5%.
