Answer:
Part 1) 0.65 more than -4.35 ----------> -3.70
Part 2) 0.65 more than -4.35 ---------> 5.11
Part 3) 4.34 added to -8 ---------------> -3.66
Part 4) 9.14 added to -9.14 -------------> 0
Step-by-step explanation:
Part 1) we have
0.65 more than -4.35
The algebraic expression is equal to the sum of the number -4.35 plus 0.65
Part 2) we have
1.98 added to 3.13
The algebraic expression is equal to the sum of the number 3.13 plus 1.98
Part 3) we have
4.34 added to -8
The algebraic expression is equal to the sum of the number -8 plus 4.34
Part 4) we have
9.14 added to -9.14
The algebraic expression is equal to the sum of the number -9.14 plus 9.14

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
