3. What percent scored $91-100$ ?

Studdy Solution

STEP 1

Assumptions1. The data provided in the table represents the test scores of30 students. . The scores are divided into intervals of10, starting from51-60,61-70,71-80,81-90, and91-100.
3. The number of students who scored in each interval can be determined by counting the scores in the table that fall within the interval.

STEP 2

To answer the first question, "How many students scored in the $91-100$ interval?", we need to count the number of scores in the table that fall within this range.

STEP 3

Count the number of scores in the table that are between91 and100.
The scores in this range are100,95,92,100,93,94.
So, there are6 scores in the $91-100$ interval.

STEP 4

To answer the second question, "How many students scored in the61-70 interval?", we need to count the number of scores in the table that fall within this range.

STEP 5

Count the number of scores in the table that are between61 and70.
The scores in this range are68,70,64,64.
So, there are4 scores in the $61-70$ interval.

STEP 6

To answer the third question, "What percent of the students scored $91-100$ ?", we need to calculate the percentage of students who scored in this range.
The formula to calculate the percentage is $Percentage = \frac{Number\, of\, students\, who\, scored\, in\, the\, range}{Total\, number\, of\, students} \times100$

STEP 7

Plug in the values for the number of students who scored in the $91-100$ range and the total number of students to calculate the percentage.
$Percentage = \frac{6}{30} \times100$

STEP 8

Calculate the percentage of students who scored in the $91-100$ range.
$Percentage = \frac{6}{30} \times100 =20\%$ So,20% of the students scored in the $91-100$ range.
