Question

Can I get help in how to work on c with Minitab. Just steps would help a lot. thank you

02 0.0 1.645 1.645 Use Minitab to create a graph showing the 90% confidence multiplier for the t with 63 degrees of freedom. Briefly explain, using what we have discussed about the t distributions, why this number is larger than 1.645. will the 95% confidence multiplier for the t with 63 degrees of freedom be larger or smaller than 1.96? (Hint You may check this with Minitab) Explain your answer using d, what we have discussed about the t distributions. 16. Notice that in the standard normal, the number 1.96 cuts off an upper tail of 0 025 (And, by symmetry, -1.96 cuts off a lower tail of 0.025) Recall that we say that 1.96

Answer 1

Solution:-

c) t = + 1.67

Degree of freedom = 63

p-value outside the tails for 90% confidence interval = 0.10

t_critical = + 1.67

This number if larger than 1.645, because the t-distributions are thicker on the tails as compared to the normal distribution.
