Identify the problem Create a hypothesisTest hypothesis against data What is the Confidence Level? What is the Significance Level? What is the representation for Null Hypothesis? What is the representation for Alternative Hypothesis? What is the main rule of a hypothesis? Hypothesis must be falsibiable A hypothesis should be mutually what...? Mutually exclusive and mutually exhaustive What is the goal with hypothesis testing? Try to reject the null What is the notation for the one-sided "greater than" alternative/one-tailed, "upper-tail" test?   What is the notation for a one-sided, "less than" alternative/one-tailed, "lower-tail" test?   What is the notation for a two-tailed test?     is the chance of what? Mistakenly rejecting a true null hypothesis What is a Type I Error? Rejecting  when it is trueToo skeptical What is a Type II Error? Accepting  what it is falseBeing too gullible  = the probability of what? P(Making a Type I Error)  = the probability of what? P(Making a Type II Error)  ? 1 What are the steps of the Critical Value approach? Set up NULL and Alternative hypothesesChoose a Significance Level Collect sample data and compute value of test statisticDetermine critical value and rejection ruleReject or fail to reject the null What does the  separate? Reject and do not reject regions What is a p-value? The probability of getting  or value more extreme What are the steps of the p-value approach? Set up NULL and Alternative hypothesesChoose a Significance Level Collect sample data and compute value of test statisticUse test statistic to compute p-valueReject or fail to reject null What is the rejection rule for a p-value? Reject  if p-value  .remove_background_ad { border: 1px solid #555555; padding: .75em; margin: .75em; background-color: #e7e7e7; } .rmbg_image { max-height: 80px; } Authorhonestkyle ID214397 Card SetStatistics Chapter 9 - Hypothesis Testing DescriptionHypothesis Tesing Updated2013-04-19T01:23:01Z Show Answers
