The test scores for the analytical writing section of a particular standardized test can be approximated by a normal distribution, as shown in the figure. (a) What is the maximum score that can be in the bottom 10% of scores? (b) Between what two values does the middle 80% of scores lie? H= 3.2 a=0.88 0.4 3.2 Score a) The maximum score that can be in the bottom 10% is . Round to two decimal places as needed.) on the low end and on the high end. b) The middle 80% of scores lies between Round to two decimal places as needed.)

ACT scores overall have a mean of 1017 and s = 207. If a college wants to admit only the top 30% of those, what score would they use as the minimum required? (Round to the appropriate whole number score). They would admit scores of and above.

A. Determine the coefficient of​ determination, r2​, and interpret its meaning. (Fill in the Blank) r2 = ___? ​(Round to four decimal places as​ needed.) B.  What is the meaning of the coefficient of​determination? (Choose Below) A. It measures the variability in the actual plate gap from the predicted plate gap. B. It measures the variability in the actual tear rating from the predicted tear rating. C. It is the proportion of the variation in the plate gap that is explained by the variability in the tear rating. D. It is the proportion of the variation in the tear rating that is explained by the variability in the plate gap. C. Determine the standard error of the estimate. SYX = ___? ​(Round to four decimal places as​needed.)

ou are doing a problem where you have a negative z-score, and you have to look up the proportion of the shaded area in the tail beyond that z-score; in other words, you are shading to the left from your z-score, and looking for the proportion that you shaded.  Four “proportions” are given below.  Which one is the ONLY one that could potentially be the number you are looking for?  (Hint: Think about what you know about proportions: What kind of number are they?  And what things can they represent?) Group of answer choices p = 0.3800 p = -0.1500 p = 1.1500 p = 0.5635
