Question 4 3 pts The Critical Value changes as we move from a two-tailed hypothes is test to a one-tailed test True False Question 5 3 pts In reference to a Confidence Interval, which are true All the answers are correct The larger the level of alpha, the smaller the Bound of Error (BOE) The larger the level of alpha, the larger the Confidence Coefficient The larger the level of alpha, the larger the standard deviation Question 8 3 pts The p-value for a Hypothesis Test of a mean or proportion All the answers are correct Is twice as large if it is a two-tailed test Is based on the probability of the test statistic on out in the relevant tail(s) of the distribution OIs compared with alpha to make a conclusion ina hypothesis test Question 10 3 pts For this problem it would be helpful to have a standard normal table. What is the z-value needed for the critical value for a one-tailed upper hypothesis test of a proportion with a sample size of 450 and alpha equal to .05? 1.645 1.28 1.96 O 2.33

Answer 1

1 question @ :- The critical value changes as we move from a two tailed hypothesis rest to a one failed test » True 1 Question 5 1 In reference to a confidence longer the interval which are true . The level of alpha, the larger is the confidence Coefficient. i question 8 | the p value for a hypothesis Test of a mean or proportion.

All the answers are correct. [ Question to for the problem it would be helpful to have a standard normal table what is a value needed for the critical value for a one failed Upper hypothesis rest of proportion with a sample size of 450 & alpha equal 1 Zdie 20.05. - 1.645] ~ (foom table)
