Chapter 6, Section 3-CI, Exercise 148 Metal Tags on Penguins and SurvivalA study was designed to test whether applying metal tags is detrimental to a penguin. One variable examined is the survival rate 10 years after tagging. The scientists observed that 10 of the 50metal tagged penguins survived, compared to 18 of the 50 electronic tagged penguins. Construct a 90% confidence interval for the difference in proportion surviving between the metal and electronic tagged penguins (pM-pE). Let pM be the proportion of penguins with metal tags that survived and pE be the proportion of penguins with electronic tags that survived.Round your answers to three decimal places.The 90% confidence interval is to .

A random sample of 100 employees at a company shows that 62 are female.  Form a 90% confidence interval for the proportion of all employees who are female.  The interval is 0.62  what margin of error?  Round your answer to 3 decimal places.

Construct a 96% confidence interval if x=75 and n=200. Round your answers to 3 decimal places.

Explain what happens when finding the margin of error if all stays the sameexcept that the confidence interval increases.

In a science fair​ project, Emily conducted an experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left​ hand, and then she asked the therapists to identify the selected hand by placing their hand just under​ Emily's hand without seeing it and without touching it. Among 337 trials, the touch therapists were correct 163 times.  Using​ Emily's sample​ results, construct a 95​% confidence interval estimate of the proportion of correct responses made by touch therapists. (round to 3 decimal places)
