Several months ago while shopping, I was interviewed to see whether or not I'd be interested in signing up for a subscription to a yoga app. I fall into the category of people who have a membership at a local gym, and guessed that, like me, many people in that category would not be interested in the app. My friend Kala falls in the category of people who do not have a membership at a local gym, and I was thinking that she might like a subscription to the app. After being interviewed, I looked at the interviewer's results. Of the 87 people in my market category who had been interviewed, 19 said they would buy a subscription, and of the 108 people in Kala's market category, 29 said they would buy a subscription. Assuming that these data came from independent, random samples, can we conclude, at the 0.05 level of significance, that the proportion p₁ of all mall shoppers in my market category who would buy a subscription is less than the proportion p, of all mall shoppers in Kala's market…
Completely abstract example: If the p-value is 0.0062 what is the conclusion (use a = 0.05)? Because the p-value is above the alpha level, we fail to reject the null hypothesis. Because the p-value is above the alpha level, we reject the null hypothesis. Because the p-value is below the alpha level, we fail to reject the null hypothesis. Because the p-value is below the alpha level, we reject the null hypothesis.
