A universityinvestigationof the amount of time required to enter the information contained in an application for admission into the university computer system (Peck and Devore (2012)). Completion times (in minutes) for 50 randomly selected applications forms were noted. The data is summarized below with a histogram and several descriptive statistics.
Mean | 7.85 |
Median | 7.40 |
Standard Deviation | 2.13 |
Completion Time (Minutes)
1. Fill in the blanks to summarize what the descriptive statistics tell me
about application entry times. Select from the options to the right of each blank.
Based on the evidence from the data, the average time required to enter admissions data was ________ (7.85 / 7.40), but the relatively large standard deviation suggests that ________ (few / many) observations differ substantially from the ________ (mean / median). The _______ (mean / median) tells us that half of the applications required less than ______ (7.40 / 7.85) minutes to enter. The fact that the ______ (mean / median) exceeds the ________ (mean / median) suggests that some unusually ________ (small / large) values in the ________ (sample / population) affected the value of the mean.
2. Write an interpretive conclusion about application entry times based on the histogram graph. Start with "Based on the evidence from the histogram..."
