Question

Modified True-False Determine whether each of the following statements is a true statement or a false statement. If it is false, change the underlined word to make it true. 26. The estimated standard deviation, s,, has n-1 degrees of freedom. 27. The expected change in the value of y for a one unit change in xis a 28. In the simple linear regression model, a and B are fixed numbers that are usually unknown. 29. The slope b of the LSRL is an unbiased estimator of the true slope p 30. Using the intercept from each LSRL a sampling distribution for the intercept of the true LSRL can be created 31. A slope of 0 means there is a perfect relationship between x and y.

28) False. Known

29) True

30) True

31) False. No relationship
