The margin of error is obtained as the ratio of the standard deviation and the square root of the sample size. It is a measure of the amount of difference that is expected to exist between the actual population value and the value obtained from the sample.
- <em>Margin of Error = ±0.01</em>
<u>Margin of Error can be calculated using the relation</u> :
Margin of Error = 0.228 ÷ √500 = 0.010
Therefore. the margin of error can be interpreted to mean that the value of the mean obtained from the sample is expected to differ from the mean of the population weight by ±0.01

Answer:
The mean of the tap water boiling point is about 2 degrees Celsius less than the mean of the salt water temperature.
Step-by-step explanation:
Boiling point is the temperature at which a liquid boils or changes from liquid form to gaseous form. Water has a boiling point of 100 degrees Celsius.
Boiling point of water depends on atmospheric pressure which changes according to the height above sea level of a place.
Boiling point can also change depending on the purity of water.Water that has impurities such as salt will have a slightly higher boiling temperature.
The mean of the tap water boiling point is about 2 degrees Celsius less than the mean of the salt water temperature.
Answer:
245/5 = 49 tickets per day
Answer:
1136/295 cm
Step-by-step explanation:
Corresponding lengths of similar figures are proportional.
If we let the radius of the second cylinder be x,
x/6.4 = 7.1/11.8
x = 6.4(7.1/11.8) = 1136/295 cm
