Question

The number of dry cleaning orders picked up at Sunny Fresh Dry Cleaners was sampled over 8 hour periods. Below is the sample:
150 164 124 98 178 164 79 126 171 164
97 133 164 124 150 111 171 93

From this data set, compute the sample mean, median, mode and mid range. Compute the 1st
quartile and 3rd and interpret their meanings.

Answer 1

i put them in order and then added them all up and divide by 18 to get the Mean.

Answer 2

mean is correct... as u calculated it

Answer 3

i need help with the mdian mode and mid range and how to compute the 1rst and 3rd

Answer 4

mode is the observation repeated the max no of times...

Answer 5

so that would be 164 because there is 4 of them

Answer 6

correct again...

Answer 7

median?

Answer 8

now u have 18 observations i.e an EVEN number of observations....

so median = average of the middle two (after they have been arranged in ascending order)

Answer 9

150 cuz there is 2 of them

Answer 10

it is mean of 9th and 10th observations
if both are 150 , then median is 150....

Answer 11

it is 133 and 150 so add them up and divide by 2?

Answer 12

just let me check if u got them in right order or not...

Answer 13

79 93 97 98 111 124 124 126 133 150 150 164 164 164 164 171 171 178
first you put them in order.

Answer 14

yes median is (133+150)/2

Answer 15

ok
now for mid range?

Answer 16

79 is lowest and 178 is highest

Answer 17

ok how do i get the 1rst and 3rd quartile and interper there meaning

Answer 18

sorry made a mistake in sign.......

highest observation + lowest observation
Mid-Range = ----------------------------------------
2

Answer 19

so it is (178+79)/2

Answer 20

ok i got the answer 128.5

Answer 21

Compute the 1st
quartile and 3rd and interpret their meanings.

Answer 22

wait sandii
i'll have to check on these terms as i am not familiar with them

Answer 23

ok .. sorry

Answer 24

first quartile is 111
third quartile is 164 (the third one from left)

sandii, you do not seem to be familiar with the terms but doing statistics. How come???

Asking, so that i can answer u better.....

Answer 25

i grasp the statistics better then i did the terms

Answer 26

Hope this explanations helps ...

First Quartile: The first quartile of a set of numbers is the value in which 25% of the numbers are below it, 75% of the numbers are above it when the numbers are arranged in ascending (increasing) order.

Third Quartile: The third quartile of a set of numbers is the value in which 75% of the numbers are below it, 25% of the numbers are above it when the numbers are arranged in ascending (increasing) order.
