Show transcribed image text Which of die following does not affect the p-value when testing statistical hypotheses'’ 4. sample sia. significance level, null hypodwsa alternative hypothesis When testing a statistical hypothesis, we cm reject 11* if a the power is greater than a. type I error is not committed. the test statistic is more extreme than the critical value a is smaller than p-value. n reporting the result of a study, a scientist claimed that listening to Mozart's music while studying significantly increases test scores (HJ. Without conducting another study, how do you reverse the scientist’s claim? I.e., what can you do to conclude that listening to Mozart while studying does not significantly increase test scores'? There's no way that this is possible Listen to Beethoven instead. Change a so it's smaller than the p-value. Sue the scientist in court Which one of the following is not true about the hypergeometric probability distribution0 There is a finite collection of objects from which n are choscn Each trial has the same probability of success TTiere arc n dependent trials. The hypergeometic random variable counts the number of successes in n trials. Tlie method of paired comparisons is useful because the two independent samples do not have to be random The effects of the extraneous factors are maximised t gives broader cor fide nee intervals because the samples are dependent A more precise estimate of the mean difference can be obtained because some extraneous factor* have been V constant
