The following data represent the monthly cell phone bill for a person's phone for six randomly selected months.
$35.34, $42.09, $39.43, $38.87, $43.39, $49.26
Compute the mean, median, and mode phone bill. (Round to the nearest cent as needed)


Sagot :

The mean of the data is x(bar) = 41.396

The Median of the data is  $40.76

The mode of all the values are appearing once and therefore there is no mode for the phone bill.

Now, According to the question:

Given the data:

$35.34, $42.09, $39.43, $38.87, $43.39, $49.26

Mean is the average of the data computed as x(bar) = Σ[tex]x_i[/tex] /n where [tex]x_i[/tex]

are the data points and n is the number of data points

x(bar) = 35.34 + 42.09 + 39.43 +38.87 +43.39 + 49.26 /  6

x(bar) = 248.38 /6

x(bar) = 41.396

The median is the data point that lies in the middle of the data set when the data is arranged in ascending or descending order.

Thus,

Ascending order:

$35.34, $38.87, $39.43, $42.09, $43.39, $49.26

The median lies between $39.43 and $42.09 and to get it, we find the average of the two numbers

Median = (39.43 + 42.09)/ 2

Median = $40.76

Mode is the value in a data set that is repeated most frequently. In the given data, all the values are appearing once and therefore there is no mode for the phone bill.

Hence, The mean of the data is x(bar) = 41.396

The Median of the data is  $40.76

The mode of all the values are appearing once and therefore there is no mode for the phone bill.
