10,11,13,18,19,21,22,25,27,30,32
Find the median of the data set.
To find the median of a data set, we need to arrange the numbers in ascending order:
10, 11, 13, 18, 19, 21, 22, 25, 27, 30, 32
Now, we count the numbers in the set to determine if there is an odd or even amount.
Since there are 11 numbers (an odd amount), the median will be the middle number when the set is arranged in ascending order.
In this case, the median is the 6th number, which is 21.
now find the lower quartile and upper quartile of the data set.
To find the lower quartile and upper quartile of a data set, we first need to arrange the numbers in ascending order:
10, 11, 13, 18, 19, 21, 22, 25, 27, 30, 32
Since there are 11 numbers in the set, we can find the lower quartile and upper quartile using the following steps:
1. Find the middle number of the lower half:
- Lower quartile position = (N + 1) / 4
- Lower quartile position = (11 + 1) / 4
- Lower quartile position = 12 / 4
- Lower quartile position = 3
2. Find the middle number of the upper half:
- Upper quartile position = 3 * (N + 1) / 4
- Upper quartile position = 3 * (11 + 1) / 4
- Upper quartile position = 3 * 12 / 4
- Upper quartile position = 9
3. Determine the lower quartile and upper quartile by taking the values at the respective positions in the sorted data set:
- Lower quartile = 13 (the 3rd value in the sorted set)
- Upper quartile = 27 (the 9th value in the sorted set)
Therefore, the lower quartile of the data set is 13 and the upper quartile is 27.
now find the percentage of people that rode the bus for less than 13
To find the percentage of people that rode the bus for less than 13, we need to determine the number of values in the data set that are less than 13 and divide it by the total number of values in the data set.
First, let's count the number of values less than 13 in the data set: 10, 11.
There are 2 values less than 13.
Next, let's calculate the percentage:
Percentage = (Number of values less than 13 / Total number of values) * 100
Percentage = (2 / 11) * 100
Percentage ≈ 18.18
Approximately 18.18% of the people in the data set rode the bus for less than 13.
the options are 25% 50% and 75%
Apologies for the confusion. To find the percentage of people that rode the bus for less than 13, we need to determine the position of 13 in the data set after arranging them in ascending order.
The data set, in ascending order, is: 10, 11, 13, 18, 19, 21, 22, 25, 27, 30, 32.
Since 13 is the third value in the sorted set, it means that 2 values are less than 13.
Now, let's calculate the percentage:
Percentage = (Number of values less than 13 / Total number of values) * 100
Percentage = (2 / 11) * 100
Percentage ≈ 18.18
Therefore, the percentage of people that rode the bus for less than 13 is approximately 18.18%.
no I SAID THE OPTIONS FOR THE PERCENTAGE IS 25% 50% AND 75%
Apologies for misunderstanding your request. Let's calculate the percentage of people who rode the bus for less than 13 based on the given options.
To find the percentage of people that rode the bus for less than 13, we need to determine the position of 13 in the data set after arranging them in ascending order.
The data set, in ascending order, is: 10, 11, 13, 18, 19, 21, 22, 25, 27, 30, 32.
Since 13 is the third value in the sorted set, it means that 2 values are less than 13.
To determine the percentage, we need to compare the number of values less than 13 (2) to the total number of values (11) in the data set.
Percentage = (Number of values less than 13 / Total number of values) * 100
Percentage = (2 / 11) * 100
Percentage ≈ 18.18
Since none of the options given (25%, 50%, or 75%) match with 18.18%, we can conclude that the percentage of people that rode the bus for less than 13 does not fall into any of the given options.
