Answer:
The correct option is;
B. With 95 percent confidence, it can be said that the repair cost is between the bounds of the confidence interval
Step-by-step explanation:
Here we have the formula for confidence interval, CI given as follows;

Where:
= Sample mean = $90.00
s = Sample standard deviation = $14.00
n = Sample size = 5
t = z value for the confidence level = 2.7764 from z-score relations
Plugging in the values, we have;

Which gives the CI as 72.6167 to 107.38.
<span>E = {x|x is a perfect square between 1 and 9} = {1,4
</span><span>F = {x|x is an even number greater than or equal to 2 and less than 9}
</span><span>D = {x|x is a whole number}
</span>
answer
D ∩ (E ∩ F) = 4
