Domain sets values and Range is the difference between the highest and the lowest numbers.
Answer:
The confidence interval = (7.8 , 8.0)
Step-by-step explanation:
Confidence Interval formula =
Mean ± z × Standard deviation/√n
Mean = 7.9
Standard deviation = 0.9
n = number of samples = 164
z = z score of an 80% confidence interval = 1.282
Confidence Interval = 7.9 ± 1.282 × 0.9/√164
= 7.9 ± 0.0900966432
Confidence Interval
= 7.9 - 0.0900966432
= 7.8099033568
Approximately to 1 decimal place = 7.8
7.9 + 0.0900966432
= 7.9900966432
Approximately to 1 decimal place = 8.0
Therefore, the confidence interval = (7.8 , 8.0)

Answer:
2703 %
Step-by-step explanation:
Step 1. Calculate the<em> markup</em>
Markup = selling price – cost
Markup = 59.99 -2.14
Markup = $57.85
===============
Step 2. Calculate the <em>percent markup
</em>
% Markup = markup/cost × 100 %
% Markup = 57.85/2.14 × 100
% Markup = 27.03 × 100
% Markup = 2703 %
The markup is 2703 %.
