Step-by-step explanation:
1. Let's order the nine scores given to us, from lowest to highest:
26 29 30 30 31 32 34 35 36
2. Now, let's calculate the percentile 66th, 70th and 78th:
A. 66th = 9 * 0.66 = 5.94 ≅ 6
Counting the sixth score from left to right, the sixth score is 32, that is not the score we're looking for.
B. 70th = 9 * 0.7 = 6.3 ≅ 6
Counting the sixth score from left to right, the sixth score is 32, that is not the score we're looking for.
C. 78th = 9 * 0.78 = 7.02 ≅ 7
Counting the seventh score from left to right, the seventh score is 34, that is not the score we're looking for.
D. 83rd = 9 * 0.83 = 7.47 ≅ 8
Counting the eighth score from left to right, the eighth score is 35, that is the score we're looking for.
The correct answer is D. 83rd.
Based on how to determine percentiles, the student who scored 35 is the 78th percentile.
To calculate the percentile, the scores are arranged in increasing order.
Step 1: Ordering the values.
26 29 30 30 31 32 34 35 36
Step 2: Calculating the percentile.
The percentile is then calculated using the formula:
Percentile = (number of values below score) ÷ (total number of scores) x 100
Percentiles = 7/9 × 100
Percentile = 77.7 or approximately 78.
Therefore, the student who scored 35 is the 78th percentile.
