Question 4The researcher wishes to use graphical descriptive methods to present summaries of the data on each of the two variables: hours worked per week and yearly income, as stored in file HOURSWORKED.jpga) The number of observations (n) is 65 individuals. The researcher suggests using 7 class intervals to construct a histogram for each variable. Explain how the researcher would have decided on the number of class intervals (K) as 7. b) The researcher suggests using class intervals as 10 < X ≤ 15, 15 < X ≤ 20, …, 40 < X ≤ 45 for the hours per week variable and class intervals 40 < X ≤ 45, 45 < X ≤ 50, ..., 70 < X ≤ 75 for the yearly income variable. Explain how the researcher would have decided the width of the above class intervals (or class width). c) Draw and display a histogram for each of the two variables using appropriate BIN values from part (b) and comment on the shape of the two distributions.
College GPA and Salary. Do students with higher college grade point averages (GPAs) earn more than those graduates with lower GPAs (CivicScience)? Consider the college GPA and salary data (10 years after graduation) provided in the file GPASalary. Develop a scatter diagram for these data with college GPA as the independent variable. PLEASE MAKE SIMPLE GRAPH. What does the scatter diagram indicate about the relationship between the two variables? Use these data to develop an estimated regression equation that can be used to predict annual salary 10 years after graduation given college GPA. At the .05 level of significance, does there appear to be a significant statistical relationship between the two variables? GPA Salary 2.21 71000 2.28 49000 2.56 71000 2.58 63000 2.76 87000 2.85 97000 3.11 134000 3.35 130000 3.67 156000 3.69 161000

Bridges covered There is a relationship between the age of a bridge in Tompkins County, New York, and its con-dition as found by inspection. Below is a graph of data. Two of bridges are considerably older than the rest. Theoldest covered bridge in daily use in New York State wasbuilt in 1853 and was recently judged to have a conditionof 4.523. Another bridge with a rating of 5.4 was built in 1865. Also below is the regression analysis for this rela-tionship using all 196 bridges. a) If we use this regression to predict the condition of theoldest bridge, what would its residual be?We removed the 1853 and 1865 bridges from the analysisand here are the results: Dependent variable is ConditionR@squared = 46.55, s = 0.7354Variable CoefficientConstant -40.7546Year 0.02343b) How were these two old bridges affecting theregression?c) The 1853 bridge was extensively restored in 1972.Does that better explain its condition?

KidsFeet Scatterplot Grouped by Sex The KidsFeet dataframe contains data collected on 39 fourth grade students in Ann Arbor, MI, in October 1997. Two of the measurements taken on the children were the length, (length), and width, (width), of their longest foot. Based on the scatterplot shown below, there appears to be a positive linear association between the length and width of a fourth grader's biggest foot that holds even when the child's sex is accounted for. Which of the following lines of code created this scatterplot (except for the title and axis labels)? ( ) xyplot(length~width, groups=sex, data=KidsFeet) ( ) xyplot(length~width, groups=sex, data=KidsFeet, auto.key=TRUE) ( ) xyplot(width~length,groups=sex,data=KidsFeet, auto.key=TRUE) ( ) xyplot(width~length, data=KidsFeet) ( ) xyplot(width~length,groups=sex,data=KidsFeet) ( ) xyplot(length~width, data=KidsFeet) ( ) xyplot(width~length|sex,data=KidsFeet) ( ) xyplot(length~width|sex, data=KidsFeet)
