A local foundation wants to promote grit in teenagers and thinks mentors would serve as good role models for young people for how to persevere when things get tough. Before they put a substantial amount of money into mentoring, they approach your program to test whether mentoring impacts grit. Of the 50 youth in your program, 25 were randomly assigned a mentor (mentor = 1), while 25 were not (mentor = 0).Six months later, you collected data from the mentees about how much grit each youth reported having (Grit) (scores range from1=not gritty at allto5=extremely gritty).

a.What is your research hypothesis?

b.What type of t-test should you use?

c.State the statistical hypotheses that you tested.

d.What was the mean reported grit for youth who were mentored and for youth who were not mentored?

e.Using a two-tailed test with ? = 0.05, what is the critical value(s) of t?

f.What is the observed value of t?

g.What is your decision in regards to the null hypothesis and why?

h.Interpret your results.
