Answer:
The correct option is;
2.81
Step-by-step explanation:
The critical value
, is found from the z score table as follows, where the the confidence level is 99.5
Therefore, we have α = 1 - 99.5/100 = 1 - 0.995 = 0.005
α/2 = 0.0025
The critical value is thus found from the z-score table value of 1 - 0.0025 = 0.9975
From the z-table, we can find the 0.9975 score on the row with z = 2.8 where 0.9975 can be located under the 0.1 column giving the critical value as 2.81
The minimum and maximum mass measurement is calculated as 1.467 kg and 1.533 kg respectively.
<h3>Minimum and Maximum mass measurement</h3>
The minimum and maximum mass measurement is determined from the uncertainty in the measurement.
For a given uncertainty of 2.2%, the minimum and maximum mass measurement is calculated as follows;
2.2% of 1.5 kg = 0.022 x 1.5 kg = 0.033 kg
minimum mass = 1.5 kg - 0.033 kg = 1.467 kg
maximum mass = 1.5 kg + 0.033 kg = 1.533 kg
Thus, the minimum and maximum mass measurement is calculated as 1.467 kg and 1.533 kg respectively.
The complete question is below:
what is the minimum and maximum mass of 1.5 kg if the uncertainty in measurement is 2.2%?
