A lower alpha value is chosen in cases where we expect more precision.
This alpha value denotes the probability of erroneously rejecting H0 when it is true. Generally a significance factor or alpha value of 0.05 is chosen. We define a significance factor to determine whether the relation between the variables is of considerable significance. We can verify the hypothesis by these methods: An alternate hypothesis would state that there is a significant relation between the two. We start by defining the null hypothesis ( H0) which states that there is no relation between the variables. The aim of the test is to conclude whether the two variables( gender and choice of pet ) are related to each other. Here, we take a table that shows the number of men and women buying different types of pets.
