On Monday, Philip rejected a null hypothesis that was true. On Tuesday, he retained a true null hypothesis. What kind of week is he having? o.k. – he made a Type I error on Monday and a correct decision on Tuesday bad – he is confounded and his power level is too low bad – he made a Type I error on Monday and a Type II error on Tuesday bad – he made a Type II error on Monday and a Type I error on Tuesday
