Based on the alternative hypothesis, the value of μ that will have the greatest test power is μ = 7.

Which value of μ will have the greatest power of test?

The alternative hypothesis is that Hₐ : μ < 14.

For the alternative hypothesis to be right, μ will have to be less than 1.4.

μ will also give a greater test power the lower it is below 14. From the options therefore, μ with the greatest test power would be 7.
