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.

do u know definition of mean median and mode?

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

median is the middle value between highest and lowest value

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

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

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

thanks evetone!!! :)!

:)

do u want step by step?

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

yes step by step please!

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

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
