An instrument has been used to measure the length of a part. The result was 6.70052 cm.

An error-of-measurement study on the instrument had the following results:

Bias: +0.00254 cm (on the average, the instrument reads 0.00254 cm high).

Repeatability (precision): 0.001016 cm (1σ).

Make a statement concerning the true value of the part just measured. State all assumptions needed.

From previous studies, it has been generally believed that Northern Hemisphere icebergs have a mean depth of 270 meters. An environmentalist has suggested that global warming has caused icebergs to have greater depth. A team of scientists visiting the Northern Hemisphere observed a random sample of 41 icebergs. The depth of the base of the iceberg below the surface was carefully measured for each. The sample mean and standard deviation were calculated to be 276 meters and 20 meters respectively....
