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...
Question 8 3 pts The a two-tailed hypothesis test Is related to a confidence interval at the same level of alpha. All of the answers are true. Is expressed in a probability framework with a chance of being wrong in our conclusion. Has an alternative hypothesis that uses Not Equal in the expression For this problem you will need a t-table. What is the t-value needed for the critical value for a one-tailed upper hypothesis test with a sample size...

What is the critical value of a right-tailed Independent t-Test when you have 32 degrees of freedom, and alpha = 0.05? (Answer to 3 digits after the decimal point.)
You may need to use the appropriate appendix table or technology to answer this question. For at distribution with 15 degrees of freedom, find the area, or probability, in each region (Round your answers to three decimal places.) (a) to the right of 1.753 (b) to the left of 2.602 0.990 (c) to the left of -2.131 (d) to the right of 1.341 (e) between -1.753 and 1.753 0.900 (1) between -2.131 and 2.131
Calculate the critical degrees of freedom and identify the critical t value for a single-sample t test in each of the following situations, using p=.05 for all scenarios. Then, state whether the null hypothesis would be accepted or rejected: 10) Two-tailed test, N = 10, t = 2.35 df= (answer) critical t = (answer) Accept or Reject Ho: (answer)
