Answer:
The train eingineer.
Step-by-step explanation:
So, to find the lifetime income, we must multiply the annual income by the years of work.
So for the cran operator:
54,830*30
=
1,644,900
Now lets compare this to the train eingineer:
50,610*33
=
1,670,130
So looking at the two numbers:
<u>1,670,130(train eingineer)</u>>1,644,900(crane operator)
So the trian eignineer makes more than the crane operator.
Now lets find the amount.
To do this, lets subtract the larger value by the smaller value:
1,670,130-1,644,900
=
<u>25,230</u>
So the train eingineer made 25,230 more dollars than the crane operator.
Hope this helps!
Answer:
Margin of Error decreases
Pvalue decreases
Power increases
Step-by-step explanation:
The margin of error decreases as sample size increases given the same level of confidence, hence, the interval gets narrower.
The margin of error = (Zcritical * σ/√n) ; where, n is the denominator, as the denomination increases, the obtained value will decrease, hence, the margin of error.
When we have a false H0, then we expect a statistical result which will reject H0, with all facts remaining unchanged , increase in sample size n, will lead to decrease in Pvalue, because a lower P value increases the significance of statistical test needed to reject H0.
The power of a fixed level test when the null hypothesis is true, higher power is required to reject the null , increasing n will increase the probability of rejecting H0, by increasing the power of a fixed level test.
I am guessing you meant 9+10 which is 19
