Question

A company samples the distribution of conductivity in isolation of receptacles and got the following values:

24.46 25.61 26.25 26.42 26.66 27.15 27.31 27.54 27.74 27.94 27.98 28.04 28.28 28.49 28.50 28.87 29.11 29.13 29.50 30.88

Trimming 10% mean when we discard the smallest and largest 10 % of the sample. Can we use that sample to calculate the point estimate of the population mean? What are the values for the estimator of the population mean with and without trim? Provide full reasoning.
