A magician began to do a trial of the YSORT method designed to increase the probability of drawing a 1 out of a two card
A magician began to do a trial of the YSORT method designed to increase the probability of drawing a 1 out of a two card deck with numbers 1 and 2.
291 attempts were made using the YSORT method and 239 of the draws were 1's. How can you use a significance level to test this claim that the YSORT method is effective in increasing the chances that a drawn card will be a 1?
- What would be the null and alternate hypotheses written mathematically? what claim supports this?
- What is the test statistic?
- What is the Rejection region (critical region) and fail to reject region? what would it be like through a drawing curve that separates the rejection region from the fail to reject region using the critical value?
- What is the p-value? what is the p-value's meaning?
- How can we decide whether to reject or fail to reject the null using the p-value approach?
- What is an interpretation of the decision in the context of the claims?
- What is a Type-1 error in this problem? What are the issues of the problem?
- Using sample data, how can a 98% confidence interval estimate of the proportion of 1's be calculated? What does the confidence interval say about the claim that the magician's YSORT method works in giving better chances that a drawn card will be a 1?
