Answer :
The 14th value in the ordered set is 21, not 89. Therefore, the student's claim is incorrect. The value 89 does not correspond to the 70th percentile in this set of values.
The 70th percentile is a measure that indicates the value below which 70% of the data falls. To determine the 70th percentile, we need to arrange the given set of values in ascending order.
The given set of values: 1 1 1 1 1 1 2 3 5 8 13 21 34 55 89 89 89 89 89 89
When we arrange the values in ascending order, we get: 1 1 1 1 1 1 2 3 5 8 13 21 34 55 89 89 89 89 89 89
To find the value at the 70th percentile, we calculate the index position by multiplying the percentile (70) by the total number of values (20) and dividing by 100:
70 * 20 / 100 = 14
The student's claim that 89 is at the 70th percentile is incorrect.
