The following statement is FALSE.  "If a model for scores on a placement test for incoming Freshman is negatively skewed and a large number of such students (say n = 200) is randomly selected, then the model for Freshman placement test scores will become approximately normal." According to the Central Limit Theorem, what quantity would have approxiately a normal distribution in this situation? i. the individual placement test scores for Freshman ii. the population mean placement test score for all Freshman iii. the sample mean placement test score for all Freshman A random sample of third grade students was selected and given a reading achievement test. The 90% confidence interval for the mean reading achievement score for the population of all third grade students is (68 points, 78 points). A. Consider the following incorrect interpretation of the 90% confidence level. Correct the interpretation by reporting which one word should be crossed out and then which one word should replace it. If we were to repeat this study many, many times, we would expect 90% of the resulting intervals to contain the sample(Population)mean reading achievement score." B.The researcher had selected a fixed level of significance of 5% to test the hypotheses H0: μ = 70 points versus the alternative Ha: μ ≠ 70 points. Would her decision be to reject H0, fail to reject H0, or can't it be determined? 1. reject H0 2. fail to reject H0 3. can't it be determined
