Step-by-step explanation:
Here we need to use the formulas for a confidence interval using a difference of 2 given proportions.
Proportion 1 (small cars) = 8/13
Proportion 2 (large cars) = 5/17
A 95% confidence level has a z-score of 1.96 (the method of looking up z-scores doesn't change with using two proportions instead of 1)
See attached photo for formulas and solutions, and the construction of the confidence interval...
Answer:
<em>75</em>
Step-by-step explanation:
Subtracting a number means adding the opposite.
The opposite of a number is the number you obtain by just changing the sign.
The opposite of 5 is -5. The opposite of 100 is -100. The opposite of -4.5 is 4.5. The opposite of 0 is 0. Zero is the only number that is equal to its opposite.
You need to subtract -45, so add the opposite of -45 which is 45.
30 - (-45) = 30 + 45 = 75
