Answer:
And the best answer on this case would be:
b) m = 4.635
Step-by-step explanation:
Let X the random variable of interest and we know that the confidence interval for the population mean 
is given by this formula:
The confidence level on this case is 0.9 and the significance 
The confidence interval calculated on this case is 
The margin of error for this confidence interval is given by:
Since the confidence interval is symmetrical we can estimate the margin of error with the following formula:
Where Upper and Lower represent the bounds for the confidence interval calculated and replacing we got:
And the best answer on this case would be:
b) m = 4.635
Answer:
$101.85
Step-by-step explanation:
Think of the two days as separate equations. They are added together to get a sum of the pay she will receive after the two days.
Equation
(4.5*10.5) + (5.2*10.5) = x (This just represents the unknown value)
Solve Through
(47.25) + (54.60) = x
47.25 + 54.60 = x
101.85 = x
Amanda will get paid $101.85 For her 2 days of work.
