In a laboratory experiment a student obtained the following values for the mass density of a metal sample: 5.13 g/cc, 4.98 g/cc,
VMariaS [17]

Answer:

5.104%

Step-by-step explanation:

Given:

The accepted value for the mass density = 4.80 g/cc

Observed values:

5.13 g/cc

4.98 g/cc

5.06 g/cc

5.01 g/cc

Total number of observed values = 4

Mean of the observed values = ( 5.13 + 4.98 + 5.06 + 5.01 ) / 4 = 5.045 g/cc

Now,

The percentage error is calculated as:

\textup{Percent Error}=\frac{\left |\textup{Accepted value-Mean value} \right |}{\left |\textup{Accpeted value} \right |}\times100%

on substituting the values, we get

\textup{Percent Error}=\frac{\left |4.80-5.045\right |}{4.80}\times100%

or

Percentage error = 5.104%

In semiconductor manufacturing, wet chemical etching is often used to remove silicon from the backs of wafers prior to metalizat
Viktor [21]

Answer:

Sample mean for solution 1:  19.27; sample mean for solution 2:  10.32

Step-by-step explanation:

To find the sample mean, find the sum of the data values and divide by the sample size.

For solution 1, the sum is given by:

9.7+10.5+9.4+10.6+9.3+10.7+9.6+10.4+10.2+10.5 = 192.7

The sample size is 10; this gives us

192.7/10 = 19.27

For solution 2, the sum is given by:

10.6+10.3+10.3+10.2+10.0+10.7+10.3+10.4+10.1+10.3 = 103.2

The sample size is 10, this gives us

103.2/10 = 10.32
