As asked by you, calculating for part b)
b. df = n-1 = 20-1 = 19
alpha = .10
So, t > -1.328 ( we use t.inv(.1, 19) formula to get this)
Similarly , for
c. nd=24 and alpha=0.10
t > -1.319 ( we use t.inv(.1, 23) formula to get this)
d. nd=6 and alpha=0.025
t > -2.571 ( we use t.inv(.025, 5) formula to get this)
e. nd=9 and alpha=0.01
t > -2.896 ( we use t.inv(.01, 8) formula to get this)
calculate for b. also calculate c. nd=24 and alpha=0.10 d. nd=6 and alpha=0.025 e. nd=9 and...

Please follow the steps of hypothesis testing, including
identifying the alternative and null hypothesis, calculating the
test statistic, finding the p-value, and making a conclusions about
the null hypothesis and a final conclusion that addresses the
original claim. Use a significance level of 0.10. Is the conclusion
affected by whether the significance level is 0.10 or 0.01?
