QUESTION 2 In which of the following situations we can not construct a confidence interval for the population proportion p? x=196 and n=200. x=11 and n= 38. x=10 and n=74. x=174 and n=260. QUESTION 3 A recent study of over 1000 parents on cyberbullying showed that a 95% confidence interval of proportion of kids who faced bullying in social media sites and apps is (0.124, 0.198). Find the point estimator of the population proportion of kids who faced bullying in social media sites and apps. Round your answer to three decimal places. QUESTION 4 The waiting time (in minutes) of customers at a fast food outlet is right-skewed. A random sample of 36 customers is selected and the 99% confidence interval for the population mean waiting time is obtained as (1.82,2.57). Find the standard deviation used to construct the 99% confidence interval. Round your anser to three decimal places.
