Answer:
= ( 50.66, 57.34)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 54 ounces
Standard deviation r = 11.7 ounces
Number of samples n = 49
Confidence interval = 95%
z(at 95% confidence) = 2
Substituting the values we have;
54+/-2(11.7/√49)
54+/-2(1.671428571428)
54+/-3.342857142857
54+/-3.34
= ( 50.66, 57.34)
Therefore, the 95% confidence interval (a,b)
= ( 50.66, 57.34)

Hello,
If the rate of return on an investment was 3% and the inflation rate was also 3%, then your buying power would remain the same. The two equal values would cancel each other out.

Good luck,
