NO.PZ2018062016000123问题如下Whiof the following statements about one-si hypothesis test is most corre?A.We rejethe null only if the evinincates ththe population parameter is smaller or larger ththe criticvalue.B. not have Type I error.C.We rejethe null only if the evinincates ththe test statistic is greater thor less ththe criticvalue.C is correct. finition, one-si hypothesis test also calleone-tailehypothesis test, whirejerule is rejethe null only if the evinincates ththe test statistic is greater thor less ththe criticvalue.想问问以下解题思路是否准确。one taile—拒绝域看Ha的符号—Ha X,则拒绝域在右边。如果Ha X,则拒绝域在左边—如果在左边,test statistic(带负号) 小于criticvalue(带负号),则rejeH0。
