Given a two-tail test for the population mean, the null hypothesis contains a(n) _______1)___ sign, and the alternative hypothesis contains a(n) _____2)______ sign.

            a. 1) =/= (not equal to), 2) =

            b. 1) =, 2) > or =

   c. 1) < or =, 2)=

   d. 1) =, 2) =/= (not equal to)

Solution

For two tailed test, null hypothesis contain = sign and alternative hypothesis contain sign. Therefore, the correct option is:

d. 1) =, 2) =/= (not equal to)
