A statistics content developer at Aplia wanted to know whether study skills are related to memory quality. She invited student volunteers to perform an online memory task. The students saw a list of 60 words and were then asked to recognize a list of 10 words that were on the original list.
Students were also asked to provide their vertical SAT scores.
Consider the following data set, which was collected from student volunteers in 2012. The table gives the frequency for the verbal SAT score intervals. Use the dropdown menus to complete the table by filling in the missing values for the proportions and percentages.
