Question

Consider the following frequency distribution:

Score	Freq
7	18
6	77
5	20
4	7
3	3
2	1
1	3

1. What was the sample size?

What percent of participants had a score of 4? of 5?
What is the score corresponding to the 80^th percentile?

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.

Suppose that a municipality creates a survey to find out how satisfied its residents are with the services provided by the city. The respondents are asked to rank their satisfaction on a scale of one to five, with one being "very dissatisfied" and five being "very satisfied". The municipality randomly selects 5000 of its 100,000 residents to complete the survey. The municipality plans to use the survey results to create a 99% large-sample z-confidence interval for the residents' satisfaction score. Complete the following flowchart to determine if all of the requirements for constructing a large-sample z-confidence interval for a proportion have been met. If your answer is no for any requirement, leave the boxes below that requirement unanswered. Is the sample a simple random sample from a large population? No Stop. Requirements are not met. Is the parameter of interest categorical with two possible outcomes? No Stop. Requirements are not met. Yes yes No Stop. Requirements are not met.…
