1.) A population of individuals with stunted growth has a mean height of 60 inches. The researchers suspect that the hormone could in a fact significantly increase people's growth. They take a sample of n= 25 individuals and give them a series of injections of a growth hormone. If the growth hormone is effective and has a LARGE effect on people's growth, then ________ . Indicate your answer (A-D below) Then explain WHY that is the answer (as though you were tutoring a fellow classmate about hypothesis testing.)
a.) The sample mean should be far from 60 and should lead you to fail to reject the null hypothesis and conclude that you have a significant effect
b.) The sample mean should be far from 60 and should lead you to reject the null hypothesis and conclude that you have a significant effect.
c.) The sample mean should be close to 60 and should lead you to fail to reject the null hypothesis and conclude that you have a significant effect
d.) The sample mean should be close to 60 and should lead you to reject the null hypothesis and conclude that you have a significant effect.
