Suppose a confidence level is 0.44 < p < 0.60
What is the value of the point estimate p-hat (round to nearest hundredth)
What is the margin of error
E= (round to the nearest hundredth)
This solution explains the value for the point estimate, and the margin of error using information about the confidence level.
Are Confidence intervals part of descriptive statistics or inferential statistics- why?
Are Confidence intervals part of descriptive statistics or inferential statistics- why? Why would we use confidence intervals instead of point estimates? Give an example of the use of a confidence interval and why you would prefer it over point estimates in your example.View Full Posting Details
