3. According to a past study from 2020 for King County, it was believed that 1.4% of the students in the Seattle Public School district did not have access to a computer. Suppose you are planning to do a follow-up study to understand the current proportion of children in Seattle Public School district that do not have access to a computer. You suspect that the proportion is probably still close to 1.4%.
How large should your sample be if you want the Margin of Error to be within 0.3% with a confidence level of 98%? (Be sure to show your calculations involving the formulas.) – Hint: Ch. 18 of the textbook has some helpful examples in a section called “Choosing your Sample Size”. Also, keep in mind that the z* value for a confidence level of 98% is 2.326.
4. What effect does each of the following have on the size of a confidence interval? i.e. For each of the following, does the confidence interval increase in size, decrease in size, or stay approximately the same size?
