Answer:
Step-by-step explanation:
A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 108, and the sample standard deviation, s, is found to be 10. (a) Construct a 96% confidence interval about μ if the sample size, n, is 17. (b) Construct a 96% confidence interval about μ if the sample size, n, is 12. (c) Construct a 90% confidence interval about μ if the sample size, n, is 17. (d) Could we have computed the confidence intervals in parts (a)-(c) if the population had not been normally distributed?
Answer:
The answer is C. Refer to my graph of all the equations. They are done in order.
Color Code:
Red - y = 1/2x^2
Blue - x^2 = 8y
Green - x - 1/8y^2 = 0
Purple - x^2 = -8y
Harold used
x1 = 7
and y1 = 0
the points are (7,0)
