A data set includes data from student evaluations of courses. The summary statistics are n= 84, x= 4.11, s= 0.56. Use a 0.10 significance level to test the claim that the population of student course evaluations has a mean equal to 4.25. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? O A. Ho: u#425 H, p=4.25 O B. Ho: u= 4.25 H,: p#4.25 O D. H, u=4.25 OC. Ho u=4.25 H,: u>4.25 H, u<4 25 Determine the test statistic. (Round to two decimal places as needed.) Determine the P-value. (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. V Hg. There is V evidence to conclude that the mean of the population of student course evaluations is equal to 4.25 V correct.

VERBAL IF-THEN'S For each of the following, do your best to figure out if the statement is true or false. Give an explanation (or argument) justifying why you think what you think. NOTE: Each of the following refers to "a number" or “numbers". They are general statements. So, if there is any number (or numbers) for which it's false, then the statement is false. In other words, if you are thinking "that's true in some cases (or perhaps even many cases), but it's not true in all cases," then the statement is false. Warning: The word "number" does not mean "integer" or "positive integer". All integers are numbers, but not all numbers are integers. Integers are numbers like -13, -4, 0, 27, and 132. Non-integers are numbers like 2.61, - 5.8, and 55/9. The first of these is between the consecutive integers 2 and 3. The second is between -6 and -5. The third is between 6 and 7. So if you are going to test the statements by choosing a number or numbers to test it with, do not limit yourself to…
