Describe the population that this sample was selected from.
Write out the research question that can be answered by the confidence interval (CI) in (a). Hint: What is the 0.44 about?
Another hint: Recall the relationship between decimal places and percentages, eg, 0.03 is 3% and 0.3 is 30%.
Describe in words the population parameter that is being estimated by the confidence interval in (a). Hint: a parameter is a stat like average or percent.
What is the margin of error for the confidence interval in (a)? Hint: To calculate margin of error (MOE), calculate the difference between the interval and divide by 2. For example, if the confidence interval is 10 to 16 then the difference = 6 (16-10), and divided by 2 = 3, so MOE is 3 in this example.
