Eroy collected data on the number of hours that each staff member at Eroy's Electronics slept Thanksgiving night. Mary the Manager slept for 999 hours, Cam the Cashier slept for 333 hours, Teddy the Truck Driver slept for 777 hours, and Sierra the Security Guard slept for 444 hours.

Find the median number of hours of sleep.
hours

Answer 1

610.5

Explanation:

First, we have to organize the data. We know that:

Mary the Manager slept for 999 hours,

Cam the Cashier slept for 333 hours,

Teddy the Truck Driver slept for 777 hours,

Sierra the Security Guard slept for 444 hours.

Next, we have to the the median number of hours of sleep.

To find the median:

First, we have to order the numbers from least to greatest. In this problem that is 333, 444, 777, 999. in an odd amount of numbers, like 5, the middle number is the median. In this case, however, there is not an odd amount of numbers, there are 4 numbers. Which means, we have to do the odd number equation:

We have to add the two middle numbers, which are 444, and 777 together, which results in 1,221. Finally, we must divide the result in half, which gives us out final total of 610.5

Hope this helped!
