Q1.

Do you read newspapers? Have you noticed how many pages a newspaper has on different days of the week — is it the same or different?

Answer

The number of pages is not the same every day. The data given for one newspaper, Monday to Sunday, is 16, 18, 20, 22, 26, 16, 10.

Day	Mon	Tue	Wed	Thu	Fri	Sat	Sun
Pages	16	18	20	22	26	16	10

Total = 16 + 18 + 20 + 22 + 26 + 16 + 10 = 128 pages
Mean = 128 ÷ 7 ≈ 18.29 pages per day

Sorted: 10, 16, 16, 18, 20, 22, 26
Median = 4th value = 18 pages

Why it happens: the page count climbs from Monday to Friday and then falls sharply. Friday is the biggest (26 pages) because that is when most advertisements are booked; Sunday is the smallest (10 pages) here. So the answer is "different" — and knowing how it differs is more useful than knowing that it differs.

Tip: mean 18.29 is only a little above the median 18. This data has no real outlier — 10 is low, but not far away from 16.

Q2.

Mark the data, the mean, and the median on the dot plot below.

Answer

The number line runs from 0 to 25 and a little beyond. Place the seven dots, stacking the two 16s, then draw the mean at 18.29 and the median at 18.

Newspaper pages, Monday to Sunday. The mean (solid) and the median (dashed) almost coincide, because the data has no strong outlier.

Why it happens: the dots spread fairly evenly from 10 to 26, with a small pile at 16. When data is spread out like this instead of being bunched at one end, the mean and median land almost on top of each other.
