Which of the following statements are TRUE? There may be more than one correct answer; select all that are true. r-p The statisticdoes not have a normal distribution. Vn The t distribution is used when ơ is not known in the statistic-_ , and must be estimated by s. Vm Replacing ơ with s results in less uncertainty and variability in the statistic Vn As the degrees of freedom increases, the shape of the t distribution becomes flatter. If the...
(1 point) Find the critical value if you are conducting a x2-right test based on a simple random sample of size 16, and using a significance level Q=0.05. The critical value is | Hint: Use Chart A4 of the 2-distribution at page 727.
Use Minitab to create graphs showing the
1-sided critical values for 0.05 and 0.01 in the
standard normal.
Considering one of the graphs you created for part a, give the
2-sided critical value for 0.10 in the standard
normal. Briefly explain your answer.
Use Minitab to create graphs showing
the 1-sided critical values for 0.05 and 0.01 in
the t with 63 degrees of freedom.
