A nurse is studying how long it takes to recover from mono without medicine. She infects three volunteers with mono (this is for science, you know) and records how long until their symptoms are gone. The data is shown below. A Do Patient 1: 7 weeks Patient 2: 51 weeks Patient 3: 53 weeks Assume normal so you can find a 96% confidence interval for the average time it takes to recover from mono. In order to solve this you need to calculate x and s. What is ? What is s? O 15.6 44 96 01 O 51 21.2 676 46 O 450.7 37 Their confidence interval would need a: ---Select--- The value for Z/t would be: O Which of the following equations is the right one for this interval?
