Question
Determine which statistical method(s) is/are appropriate to answer the question(s). You do not need to perform any actual analyses. Just state the method(s) that will best answer the questions. Give a one sentence explanation for your choice in each case. (You may assume all necessary assumptions are met, such as normality, common variance, etc., when they apply.) Your choices are:
Hypothesis tests and/ or confidence intervals
for a single population proportion to compare two population means using independent samples
for a single population mean to compare two population proportions
for a single population variance to compare two population means using paired data
to determine independence/dependence of rows and columns in a table
Checking for the existence of a linear relationship with a scatter plot and correlation
Q)In a recent survey of 1000 American adults, respondents were asked what they miss most during an electrical power outage. Of the respondents, 134 said they missed their computer’s internet access the most. An internet service provider wants to use this to estimate the actual percentage of Americans who feel this way. What method should they use?
