Question

How large is a wolf pack? The following information is from a random sample of winter wolf packs. Winter pack size are given below. Compute the mean, median, and mode for the size of winter wolf packs.(Enter your answers to one decimal place.) 9 17 14 12 14 14 9 11 10 20 10 22 11 11 9 15 14 15 mean 13.1 Mean: _____Median: _____Mode: _____

Answer 1

Answer:

mean=13.2

median=13

mode=14

Step-by-step explanation:

mean=sum of values/number of values

sum of values=9+17+14+12+14+14+9+11+10+20+10+22+11+11+9+15+14+15=237

number of values=18

mean=237/18=13.17

Mean=13.2

Arranging data in ascending order

9 9 9 10 10 11 11 11 12 14 14 14 14 15 15 17 20 22

n/2=18/2=9 is an integer so,

median= the average of (n/2)th and (n/2 +1)th observation

median=(12+14)/2=26/2=13

Median=13

Mode= The most repeated observation in the data

14 is repeated more than other numbers so, 14 is the mode for this data.

Mode=14
