    Researchers randomly assigned 1000 hospitalized patients older than 50 to receive either 40mg of Med A per day, 20 mg of Med A per day or placebo to prevent venous embolism.

    See attached.

    1. State the null and alternative hypothesis of each test reported in the table above.

    2. Are the p-value of each of the test reported in the table above less than 5%? Justify your answers.

    3. Interpret the 1.02(0/07-1.51) appearing under 20 mg of Med A. Your interpretation must contain the three "values", i.e. 1.02, .7, 1.51.

    4. Interpret the 0.37(0.22-0.63) appearing under 40 mg of Med A. Your interpretation must contain the three "values", i.e. 0.37, 0.22, and 0.63.

    1. Null hypothesis: the relative risk under 20 mg of Med A is equal to 1
    Alternative hypothesis: the relative risk under 20 mg of Med A is not equal to 1

    Null hypothesis: the relative risk under 40 ...

    Solution Summary
