5000*0.03+0.05x=275
Solve for x
X=2500
The answer is b
Answer:
Var(X)=1.6
Step-by-step explanation:
Formula for calculating the coefficient of variation for a probability generating function:
Var(X)= PX''(1) + PX'(1) - [PX'(1)]² ........... eq(1)
Now compute each individual term in the above formula.
PX'(z) =
PX'(1) = = 8
[PX'(1)]² = 64
PX''(z) =
PX''(1) = = 57.6
Substitute all terms back in eq(1)
Var(X)= 57.6 + 8 - 64
Var(X)= 1.6
Answer:
Kindly check explanation
Step-by-step explanation:
The power of a test simply gives the probability of Rejecting the Null hypothesis, H0 in a statistical analysis given that the the alternative hypothesis, H1 for the study is true. Hence, the power of a test can be referred to as the probability of a true positive outcome in an experiment.
Using this definition, a power of 90% simply means that ; there is a 90% probability that the a Pvalue less Than the α - value of an experiment is obtained if there is truly a significant difference. Hence, a 90% chance of Rejecting the Null hypothesis if truly the alternative hypothesis is true.
yeah it does because $68,000 is a numerical description of a sample of annual salaries. so it is only a PARAMETER
