They were then asked to list all the objects they could remember. The summary statistics for each group are shown in the table. Complete parts a and b. OA. Ho: HM-HR=0 HA: HM-HR0 OC. Ho: HM-HR <0 HA: HM-HR=0 33 Count Mean 10.88 SD 3.71 Test the hypothesis. t = -0.78 (Round to two decimal places as needed.) P= (Round to four decimal places as needed.) Rap a) Does it appear that it is better to study while listening to Mozart than to rap music? Test an appropriate hypothesis and state your conclusion.
