Answer:
Standard error = 0.34
t-statistic = 11.18
Step-by-step explanation:
Given Data:
Mean difference d = 3.8
Standard deviation S.D = 1.36
Number of people = 16
The appropriate test are:
1. Standard error
2. T- statistic
1. Calculating the standard error using the formula;
Standard error = S.D/√n
= 1.36/√16
= 1.36/4
= 0.34
2. Calculating the t-statistic using the formula;
t-statistic = d/(S.D/√n)
= 3.8/(1.36/√16)
= 3.8/(1.36/4)
= 3.8/0.34
= 11.18
Answer:
11
Step-by-step explanation:
If RS=TV
5x-9=2x+3
5x-2x=3+9
3x=12
x=4
RS is 5x-9
5(4)-9
20-9

Answer:
The integral diverges
Step-by-step explanation:
∫₋₁¹ 10/x² dx
There is a discontinuity in the function at x = 0. Splitting this into two integrals:
∫₋₁⁰ 10/x² dx + ∫₀¹ 10/x² dx
-10/x |₋₁⁰ + -10/x |₀¹
∞
