To find the mean proportion of left-handed people in the sample, we can use the expected value of the sample proportion. The expected value of the sample proportion is equal to the population proportion.Given that the proportion of people who are left-handed is 0.12, the mean proportion of left-handed people in the sample should also be 0.12.Therefore, the mean proportion of the sample who should be left-handed is 0.12.
