Conduct a full hypothesis testing on the following problem and then choose among the options what best fits the items being asked: A medical bulletin reports that the average cost of rehabilitation for stroke victims is PhP 750,000. To see if the average cost of rehabilitation is different from a certain hospital, a researcher selects a random sample of 35 stroke victims at the hospital and finds that the average cost of their rehabilitation is PhP 680,000 with a standard deviation of PhP 100,000. At a-0.01, can it be concluded that the average cost of stroke rehabilitation at that certain hospital is lower from the reported cost from the medical bulletin? Note: Round off the test statistic to 3 decimal places. If two-tailed test is to be applied, the given critical values as options are considered the absolute values. Identify the following: - Alternative Hypothesis: H PhP 750,000 . Critical Value: -2.575 - Test Statistic: -4.141 - Decision: Reject Ho <> (> <>
