Math Problem Statement

Calculate estimates of the mean and standard deviation of the data, giving your answers correct to 2 decimal places. Hence identify any outliers that are more than two standard deviations from the mean.

Solution

The question in the image asks for the following steps:

  1. Calculate the mean and standard deviation of a dataset (not included in the snippet but likely provided elsewhere). Answers must be correct to two decimal places.
  2. Identify any outliers, defined as values more than two standard deviations from the mean.

To proceed, I need the data or dataset referred to in this question. Could you share the numbers or clarify their source?
