- Suppose we wish to calculate an 80% confidence interval. What would be the value of z in the confidence interval equation p(1-p) p ± ²√ -? Use the z-score table to find it. Your answer should be correct to within 0.01. Your value of z should be positive. nQuestion 20 Wildlife biologists inspect 153 deer taken by hunters and find that 32 of them carry ticks that test positive for Lyme disease. For the correct 95% confidence interval for the population proportion, which of the following would be a valid conclusion? O a. We know for sure that the true proportion of Lyme disease carrying ticks is within the calculated interval O b. We know that 95% of deer carry ticks with Lyme disease O c. We are 95% confident that the true proportion of Lyme disease carrying ticks is 0.21? O d. We are 95% confident that the true proportion of deer that carry ticks with Lyme disease is within the calculated confidence interval «< Que A Moving to another question will save this response. dtv 20 吕口 F3 FS F7 FB F9 esc F2 F1 @ 2$ % & * 4 7 8.

- QUESTION 16 In 2005, Health Canada claimed that 16.6% of Canadian adults are obese. A researcher wanted to check whether this percentage has increased in 2009. He randomly selected 160 Canadian adults and found 30 of them are obese. He wants to develop a 92% confidence interval for the obese percentage in 2009. Write down the critical valueQUESTION 17 Suppose an internet marketing company wants to determine the current percentage of customers who click on ads on their smartphones. A random sample of 1000 customers is selected and 120 of them click on ads on their smartphones. Find the upper confidence limite (UCL) of the 98% confidence interval estimate for the population proportion of customers who click on ads on their smartphones. Round your answer to three decimal places.Question 6: The confidence interval is reported as follows: Lower 95% CI < p < Upper 95% CI For this question you will be calculating the confidence interval but only reporting the Upper 95% CI using the Agresti-Coull Method. ( (you'll need to know the whole 95% CI for a future question) In the Invisible Gorilla Experiment, 35 students were watching the video, only 5 noticed the gorilla. Calculate the 95% CI using the Agresti-Coull method, but only report the Upper 95% CI. Report your answer to 3 decimals.
