Fifty pro-football rookies were rated on a scale of 1 to 5, based on performance at a training camp as well as on past performance. A ranking of 1 indicated a poor prospect whereas a ranking of 5 indicated an excellent prospect. The following frequency distribution was constructed. Rating Frequency 1 4 2 10 3 14 4 18 5 4
Fifty pro-football rookies were rated on a scale of 1 to 5, based on performance at a training camp as well as on past performance. A ranking of 1 indicated a poor prospect whereas a ranking of 5 indicated an excellent prospect. The following frequency distribution was constructed.
| Rating | Frequency |
| 1 | 4 |
| 2 | 10 |
| 3 | 14 |
| 4 | 18 |
| 5 | 4 |
a-1. How many of the rookies received a rating of 4 or better?
a-2. How many of the rookies received a rating of 2 or worse?
b-1. Construct the corresponding relative frequency distribution. (Round your answers to 2 decimal places.)
b-2. What percent received a rating of 5?
c. Construct a bar chart for this data. (Before plotting the points, round the "Relative Frequency" to 2 decimal places. Click on the x-axis exactly below the "0" point and then drag the bar till it reaches the correct answer.)
