Direction: Formulate the null and alternative hypothesis of the given problem. Find the given data, solve the t- computed or z-computed (show your solution), make a decision, and state the conclusion. (NOTE: USE THE TABLE BELOW FOR IDENTIFYING THE Z-TABULAR OR T-TABULAR) 1. Two groups of experimental rats were injected with tranquilizer at 1.0 mg. and 1.0 mg 1.5mg dose dose 1.5 mg. dose respectively. The time given in seconds that 9.8 12.0 took them to fall asleep is hereby given. The researcher what's to test the difference 13.2 7.4 in dosage has no effect on the length of time it took them to fall asleep. Use 1% level 11.2 9.8 of significance 9.5 11.5 13.0 13.0 12.1 12.5 9.8 9.8 a.
