Question

kellen and his classmates recycle in one week at school. here is the graph he created to display the data he collected. please title the bar graph and label the x - and y - axis. complete the data to show the data kellen collected, then answer the questions using the data.

monday	tuesday	wednesday	thursday	friday

what is the total mass of the paper kellen and his classmates collected?
which number is the outlier in this set of data? why might this number be so different than the other data that was collected?

Explanation:

Step1: Identify the data values

The amounts of paper recycled each day are: Monday - 250 grams, Tuesday - 300 grams, Wednesday - 150 grams, Thursday - 250 grams, Friday - 0 grams.

Step2: Calculate the total mass

Add all the values together: $250 + 300+150 + 250+0$.
$250+300 = 550$, $550+150=700$, $700 + 250=950$, $950+0 = 950$ grams.

Step3: Identify the outlier

An outlier is a data - point that is significantly different from other data points. Here, 0 (Friday's value) is the outlier as all other values are non - zero and relatively large. Reasons for it being different could be that there was no recycling activity on Friday, or there was an error in data collection for that day.

Answer:

The total mass of the paper collected is 950 grams. The outlier is 0 (Friday's value) and it might be different due to no recycling activity or data collection error on Friday.
