Grade: 9-a Lesson: S4-L8 |
Explanation: Hello Students, time to practice and review the steps for the problem. |
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
If X is a Uniform variate with the parameter 50 and 100, find the mean, median and standard deviation. |
|
2 |
Formula: |
Uniform distribution For X∼ U(a,b) f(x) = \$1/(b-a)\$ a<x<b |
|
3 |
Step |
From the given data |
a = 50 ,b = 100 |
4 |
Formula: |
mean = median = \$(a+b)/2\$ |
|
5 |
Step |
Substitute the values in formula |
\$(50+100)/2\$ |
6 |
Step |
mean = median = |
\$150/2\$ |
7 |
Step |
mean = median = |
75 |
8 |
Formula: |
Standard deviation = \$\sqrt((b-a)^2/12)\$ S.D.= \$(b-a)/\sqrt12\$ |
|
9 |
Step |
Substitute the values in formula |
\$(100-50)/\sqrt12\$ |
10 |
Step |
Standard deviation |
\$50/\sqrt12\$ |
11 |
Step |
Standard deviation |
\$50/3.464\$ = 14.434 |
