<h3>What is a relative frequency table?</h3>
A relative frequency table is a graph that depicts the popularity or pattern of a certain piece of data based on the population sampled.
When we examine the relative frequency, we examine the number of times a certain event happens in comparison to the overall number of events.
We have the following equation for the adult column;
Hence the value of x will be 85.

Answer:
a. Identify the population of interest in this study.
- all the population of the country
b. Identify the sample for the study.
- 50 adults (the ones that were surveyed)
c. Identify the parameter of interest in the study.
- the parameter of interest is the people that believe that coffee shops are overpriced
d. Find and interpret a 95% confidence interval for the parameter of interest.
z score for a 95% confidence level = 1.96
margin of error (E) = z score x √{[0.4(1 - 0.4)] / 50} = 1.96 x 0.069282 = 0.13579
95% confidence level interval:
0.4 - 0.13579 = 0.26421
0.4 + 0.13579 = 0.53579
- 95% confidence interval (0.26421 , 0.53579)
Answer:
Scale factor is 3
Step-by-step explanation:
The distance in A and B is 2
The distance in A' and B' is 6
