Answer:
97% confidence interval for the survey is between a lower limit of 0.45 and an upper limit of 0.67
Step-by-step explanation:
Confidence Interval is given by the mean + or - error margin
The lower limit of the confidence interval is found by subtracting the error margin from the mean.
The upper limit is obtained by adding the error margin to the mean.
The interpretation is that the mean is between 0.45 and 0.67
To find a perpendicular slope (or line), the slope (in this case 4x) must be the opposite sign and its reciprocal, which is basically the fraction flipped upside down. Since 4 is technically 4/1, that fraction flipped is 1/4. And since you need to flip the sign too, instead of it being a positive number, it's negative. Your answer is -1/4x-8
