The following 10 measurements are made of the output voltage from a high-gain amplifier that is contaminated owing to noise fluctuations: 1.53, 1.57, 1.54, 1.54,1.50, 1.51, 1.55, 1.54, 1.56, 1.53...

The following 10 measurements are made of the output voltage from a high-gain

amplifier that is contaminated owing to noise fluctuations:

1.53, 1.57, 1.54, 1.54,1.50, 1.51, 1.55, 1.54, 1.56, 1.53

Determine the mean value and standard deviation. Then, estimate the accuracy to

which the mean value is determined from these 10 measurements. If 1000 measurements were taken instead of 10, but s remained the same, by how much would the

accuracy of the calculated mean value be improved?
