Answer:
For c=5 there are not solutions for the compound inequality
Step-by-step explanation:
we know that
In the compound inequality
-----> inequality A
-----> inequality B
The solution of the system of inequalities must satisfy inequality A and must satisfy inequality B
so
If c=5
then
There is no solution that satisfies both inequalities simultaneously.
therefore
For c=5 there are not solutions for the compound inequality

Step-by-step explanation:

Answer:


Step-by-step explanation:
For this case we have the following data given:
2.3 3.1 2.8
1.7 0.9 4.0
2.1 1.2 3.6
0.2 2.4 3.2
Since the data are assumedn normally distributed we can find the standard deviation with the following formula:

And we need to find the mean first with the following formula:

And replacing we got:

And then we can calculate the deviation and we got:

Answer:
See below.
