Question

use 6-point bins (94 to 99, 88 to 93, etc.) to make a frequency table for the set of exam scores shown below. include columns for relative frequency and cumulative frequency. 97 69 78 80 83 73 80 68 85 69 83 77 73 89 83 74 74 85 87 97 complete the frequency table below. scores frequency relative frequency cumulative frequency 94 to 99 2 10 % 2 88 to 93 %

Explanation:

Step1: Count scores in 88 - 93

Check each score: 89 is in 88 - 93. Others: 97,69,78,80,83,73,80,68,85,69,83,77,73,83,74,74,85,87,97. So only 89. Frequency = 1.

Step2: Calculate relative frequency

Total scores: 2 (94 - 99) + 1 (88 - 93) +... Wait, total scores: let's count all. Given scores: 97,69,78,80,83,73,80,68,85,69,83,77,73,89,83,74,74,85,87,97. That's 20 scores. Relative frequency = (1/20)*100 = 5%.

Step3: Calculate cumulative frequency

Cumulative frequency for 88 - 93 is previous cumulative (2) + current frequency (1) = 3.

Answer:

For 88 to 93: Frequency = 1, Relative Frequency = 5%, Cumulative Frequency = 3.
