STATISTICS

A researcher studying the behaviour of mice has recorded the time (in seconds) taken by each mouse to locate its food by considering 13 different mice as 31, 33, 63, 33, 28, 29, 33, 27, 27, 34, 35, 28, 32. Find the median time that mice spent in searching its food.

Median time spent by mice in searching it's food = 32

Arranging the time taken by the 13 mice in increasing order -

27,27,28,28,29,31,32,33,33,33,34,35,63

The total number of observations is 13(odd).

For odd number of observations the median is equal to the middle term of the observations.

Median time spent by the mice searching for food = 7th term = 32

Median time spent by mice in searching it's food = 32

Arranging the time taken by the 13 mice in increasing order -

27,27,28,28,29,31,32,33,33,33,34,35,63

The total number of observations is 13(odd).

For odd number of observations the median is equal to the middle term of the observations.

Median time spent by the mice searching for food = 7th term = 32

Step-by-step explanation:

fourth month

step-by-step explanation:

it is the one with the most keychains.

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.
