Question

The number of baby deliveries in a small hospital was sampled over 6 hour periods. Below is the sample:
11 12 7 16 4 8 9 7 3 4
9 4 6 12 9 8 4 6 12

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

Answer 1

do u know definition of mean median and mode?

Answer 3

mean is average so add em and divide by number of data entered

Answer 4

median is the middle value between highest and lowest value

Answer 5

mode is the most frequent number that occurs in the list so just look at it

Answer 6

3 4 4 4 4 6 6 7 7 8

8 9 9 9 11 12 12 12 16

mean = 151/19

median = (19+1)/2 or tenth term

mode is the mst frequent =4

midrange (16-3)/2 = 7.5

1st quartile = (19+1)/4 or the 5th term

3rd quartile = 9

Answer 7

11+12 +7+16+4+8+9+7+3+4+9+4+6+12+9+8+4+6+12=151
total 19 values
Mean = 151/19 =7.94736842
Arranging in ascending order
3,4,4,4,4,6,6,7,7,8,8,9,9,9,11,12,12,12,16.
Total 19 values.
Median is the 10th value = 8
Mode is the data that appears maximum number of times = 4
Median 8 divides the data into two halves.
Median of 3,4,4,4,4,6,6,7,7,8 is the 5th value = 4 is the 1st quartile.
Median of 8,9,9,9,11,12,12,12,16 is the 5th value = 11 is the third quartile

Answer 8

thanks evetone!!! :)!

Answer 9

:)

Answer 10

do u want step by step?

Answer 11

first Arrangethe numbers in ascending order

3 4 4 4 4 6 6 7 7 8

8 9 9 9 11 12 12 12 16

Answer 12

yes step by step please!

Answer 13

u hav 19 numbers now

for the mean, u add up all the numbers and divide it by hw many numbers ther are

so
11+12 +7+16+4+8+9+7+3+4+9+4+6+12+9+8+4+6+12=151

so the mean is
151/19 = 7.947

Answer 14

the median is the middle value
(19+1)/2 = 10th value, which is 8
Mode is the most frequent number which = 4
the mid range is the (largest value-lowest value)/2 = (16-3)/2=7.5

1st quartile = (19+1)/4 =the 5th term

3rd quartile = 3/4 ( 19+1) =15th term
