Describe your target population, your approach to sele A Imagine that you're working for a pharmaceutical company developing a new Covid-19 vaccine. The company is ready to start human testing of its Covid-Vac vaccine, and you are responsible for selecting the test participant, collecting, analyzing and reporting the testing results. The initial test is planned for 150 volunteers. 1. Describe your target population, your approach to selecting a sample of 150 test participants, the type of information you will be collecting. 2. The vaccine tests show that 120 people out of 150 vaccinated have developed resistance to the Covid-19 virus. Prepare a brief report describing the results, including the "vaccine protection ratio (percentage of vaccinated people who develop resistance to the virus), Standard Error of sampling and a 95% Confidence Interval.

Answer 1

using excel>addin>phstat>confidence interval> estimate for proportion

we have

Confidence Interval Estimate for the Proportion
Data
Sample Size	150
Number of Successes	120
Confidence Level	95%
Intermediate Calculations
Sample Proportion	0.8
Z Value	-1.9600
Standard Error of the Proportion	0.0327
Interval Half Width	0.0640
Confidence Interval
Interval Lower Limit	0.7360
Interval Upper Limit	0.8640

95% confidence interval is (0.7360 , 0.8640)

we are 95% confident that the vaccone protection ratio lies in between 73.6% to 86.4%
