Try it on paper first. A hint, the key idea and the worked solution are here when you need them.

Put the 30 days into groups of two degrees: $26$ to $27$ , $28$ to $29$ , $30$ to $31$ , $32$ to $33$ and $34$ to $35\ ^\circ\text{C}$ . Count the days in each group and find each relative frequency.

The month, in degrees Celsius: $31, 32, 30, 33, 34$ , $33, 31, 29, 28, 30$ , $32, 33, 35, 34, 32$ , $31, 30, 29, 28, 27$ , $29, 31, 32, 33, 31$ , $30, 28, 27, 29, 30$ . It rained on days $8, 9, 10$ , $17$ to $20$ and $27$ to $29$ .

The worked solution

Have you tried it?

Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.

← All Problems

← A weather station records these. Say whether each is numerical or categorical, and then whether it…Find the mean, the median and the mode of the temperatures on the 10 rainy days. →
