Smoking 2009, women and men In Exercise 2, we ex-amined the percentage of men aged 18–24 who smoked from 1965 to 2009 according to the Centers for DiseaseControl and Prevention. How about women? Here’s ascatterplot showing the corresponding percentages forboth men and women:a) In what ways are the trends in smoking behaviorsimilar for men and women?b) How do the smoking rates for women differ fromthose for men?c) Viewed alone, the trend for men may have seemed toviolate the Linearity Condition. How about the trendfor women? Does the consistency of the two patternsencourage you to think that a linear model for thetrend in men might be appropriate? (Note: there is nocorrect answer to this question; it is raised for you tothink about.)

PhD (2013) Basic Statistics for Health Science Courses by RALO Mendor, PhD (2013) In table 3, the class site or class width used is 15. 80, 95, 110, 125 and 140 are called the lower class limits while 94, 109, 124, 139 and 154 are called the upper class limits. In the class boundary 79.5-94.5, 79.5 is the lower class boundary 94.5 is the upper class boundary. The class mark is obtained by getting the average of the lower and the upper class boundary which is (79.5+ 94.5)/2-87 for the score 80-94. An accurate class width or class interval can then be obtained by getting the difference between the upper and the lower boundary which is 94.5-79.5 15 for the The range (R) for a grouped data is computed by getting the difference of the highest value of the upper boundary and the lowest value of the lower boundary. For the data given above, the range (R) 154.5-79.5-75. Table 3 is a type of frequency distribution that is useful in calculating other descriptive properties of score 80.94 and so…

Question 19 Lucille, Rocio, and Cristina are all taking College Mathematics but from different professors. They all recently took a statistics exam and the exam scores were normally distributed in each of their classes. • Lucille's class had an average grade of 77 and the standard deviation was 4. Lucille earned 84.2 on the exam. Rocio's class had an average grade of 85 and the standard deviation was 3. Rocio earned 85.6 on the exam. Cristina's class had an average grade of 85 and the standard deviation was 5. Cristina earned 91.5 on the exam. Since some professors give harder exams than others, these students decided to use statistics to figure out who did the best on their exam. Use the Cumulative Z-Score Table to answer the following questions. Write your answers as a percent with two decimal places. Hint • Lucille's score places her above % of her class. % of her class. Rocio's score places her above % of her class. • Cristina's score places her above Which person has the highest…
