## Exam-Style Question on Statistics## A mathematics exam-style question with a worked solution that can be revealed gradually |

Question id: 112. This question is similar to one that appeared on a IGCSE Extended paper in 2014. The use of a calculator is allowed.

155 people were asked how much money they would pay for particular three-course meal in a special restaurant.

The histogram shows the results of the survey.

(a) Complete the frequency table for information shown in the histogram.

Amount (£\(x\)) | \(0\lt x \le 10\) | ||||
---|---|---|---|---|---|

Frequency | 20 |

(b) Use your frequency table to calculate an estimate of the mean amount these people would pay for the meal.
