According to an article in Science Daily (“Still No Strong Evidence That Adjunct Treatment with HGH in IVF Improves Results,” sciencedaily.com, July 4, 2016, retrieved November 26, 2016), women who are having difficulty becoming pregnant sometimes use human growth hormone (HGH) in addition to in-vitro fertilization (IVF) to try to have a baby.

A large study found that “there was no strong evidence” that the proportion of women who became pregnant while taking HGH along with IVF was greater than the success rate for IVF alone.

a. Is this consistent with testing 

H₀: HGH in addition to IVF increases the chance of getting pregnant versus

H_a: HGH in addition to IVF does not increase the chance of getting pregnant or with testing

H₀: HGH in addition to IVF does not increase the chance of getting pregnant versus

H_a: HGH in addition to IVF increases the chance of getting pregnant Explain.

b. Does the stated conclusion of “no strong evidence” indicate that the null hypothesis was rejected? Explain.
