Question 1: Suppose you select a simple random sample of 80 Douglas College students. You find that 11 are left-handed. What is the best point estimate of p= the proportion of Douglas College students who are left-handed?
![QUESTION 4
(Continuing Question 1) Calculate the margin of error E (at the 99% confidence level). Round your answer to four decimal places.
QUESTION 5
(Continuing Question 1) What is the 99% confidence interval for the proportion p = the proportion of left-handed students at Douglas
College?
O a. (0.062, 0.213)
O b.(0.038, 0.237)
Ос. (-0.061, 0.336)
O d.(-0.0992, 0.0992)
QUESTION 6
What is the correct interpretation of the specific interval (a,b) that you found in Question 5?
O a. There is a 99% probability that p lies in the interval (a,b).
O b. For 99% of all possible samples, 6 for that sample lies in the interval (a,b).
O c. For 99% of all possible samples, if we follow the procedure in Questions 1 to 6, then ô lies in the resulting interval.
O d. For 99% of all possible samples, if we follow the procedure in Questions 1 to 6, then p lies in the resulting interval.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb1e5e910-f5f3-4acc-89c3-4d4c24b2c124%2F644c2a70-5909-4d59-922a-ff4c165521e7%2Frq4tlo_processed.png&w=3840&q=75)

Step 1
Confidence interval:
It is defined as the range which contains the value of true population parameter. The confidence interval is constructed for various population parameters like population mean, population standard deviation and so on.
The confidence interval can be interpreted as : With a stated level of confidence, it can be said that the true population parameter for which confidence interval is constructed lies with the obtained confidence interval.
