180.9, 181.6, 184.8, 185, 182.7, 182, and 182.7.

Find the best estimate for the length of the table. Enter answer in centimeters.

2. Seven measurements of the length of a table in centimeters are

182.3, 183.5, 183.7, 180.7, 180.1, 184.8, and 184.5.

Find the standard deviation of the measurements. Enter answer in centimeters.

3. Seven measurements of the length of a table in centimeters are

183.3, 184.8, 184.2, 182.3, 183.8, 183.4, and 183.2.

Find the uncertainty in the average of the measurements. Enter answer in centimeters.

Answer 1

1) For best estimate of the quantities we will calculate the mean of the quantities.

Mean = Sum of quanties / no of quantities.

2)

Standard deviation of the values can be calculated as,

3)

Uncertainty in the average can be found as,
