Determine whether you think they have a positive or negative correlation.Usually as a car increases in age, its value decreases.Usually the more hours that a person works the larger their paycheck.Usually the younger a child is, the smaller their height.Usually the longer you use a smart phone, the amount of battery life decreases. Consider the following situations and answer the following True or False Questions.A researcher noticed a relatively strong positive correlation between a student’s score on the SAT and their GPA at the high school they attend. If one student has one of the lower SAT scored at one high school then they probably have one of the higher GPA’s at their school.If one student has the highest SAT score at one high school then they must have the highest GPA at their high school too.If one student has one of the higher SAT scores at one high school then they probably have one of the higher GPA’s at their school.??Student Number12345678910Hours Slept8778657497Test Score83867488766390608981 A history teacher asked her students how many hours of sleep they had the night before a test. The data above shows the number of hours the student slept and their score on the exam. The graph is a scatter plot from the given data.Does this graph exhibit a linear or non-linear pattern? Is the graph representing a positive or negative relationship?Would this information affect your behavior the night before a test?Does this imply a cause and effect relationship?2. The following chart shows violent crime rates compared to high school graduation for all fifty states.Is this an illustration of cause and effect, or are these two variables simply correlated? ................
