Find the median, lower quartile, and upper quartile for the given set of data. {23.5, 22.1, 24.0, 28.6, 26.3, 29.2, 21.0, 22.7, 25.5, 22.3, 21.6} a. lower quartile = 21.0, median = 23.5, upper quartile = 29.2 b. lower quartile = 21.0, median = 24.3, upper quartile = 29.2 c. lower quartile = 22.1, median = 23.5, upper quartile = 26.3 d. minimum = 22.1, median = 24.3, upper quartile = 26.3

Option C

Step-by-step explanation:

We have to find the median, lower quartile and upper quartile for the given set of data and arrange data set from lowest to greatest.

21.0, 21.6, 22.1, 22.3, 22.7, 23.5, 24.0, 25.5, 26.3, 28.6, 29.2

Median : To find the median first we arrange data in ascending order and middle number is median. so Median is 23.5

Lower quartile (Q1) : Median of the lower half of the data is called Lower quarlile. Q1 = 22.1.

Upper quartile (Q3) : Median of the upper half of the data is called upper quartile. Q3 = 26.3

Option C : Median: 23.5, Lower quartile: 22.1, Upper quartile: 26.3

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
