A lab class conducts a 1000 trial scattering probability experiment. Nine (9) target marbles were used on a 45.0 cm wide board. The marble diameter was calculated to be 1.48 cm.
How many hits were recorded during the experiment?
If the standard value for the marble diameter is 1.57 cm, what is the percent error in the experimental marble diameter?
To calculate the number of hits recorded during the experiment, we need to know the scattering probability and the number of trials. However, the question does not provide information about the scattering probability. Can you please provide the scattering probability or any additional information that might help us calculate the number of hits?
To calculate the percent error in the experimental marble diameter, we can use the following formula:
Percent Error = ((Experimental Value - Accepted Value) / Accepted Value) * 100
In this case, the accepted value is the standard value for the marble diameter, which is 1.57 cm. The experimental value is given as 1.48 cm.
Substituting these values into the formula, we get:
Percent Error = ((1.48 - 1.57) / 1.57) * 100
Calculating this expression, we find:
Percent Error = (-0.09 / 1.57) * 100
Percent Error = -5.7
Therefore, the percent error in the experimental marble diameter is approximately -5.7%.
