Answer:
(21.064 ; 23.136)
Step-by-step explanation:
Given :
Sample, n = 80
Mean, xbar = 22.1
Standard deviation, s = 5.6
Standard Error, S. E = 0.63
Confidence interval :
Xbar ± Zcritical * S.E
22.1 ± (1.645 * 0.63)
22.1 ± 1.036
Lower boundary = 22.1 - 1.036 = 21.064
Upper boundary = 22.1 + 1.048 = 23.136

A time-series plot is a graphical representation in which the measure of time is expressed on the x-axis and what is to be measured is represented on the y-axis.
A time-series plot also known as a line chart helps to depict data from any event that has been gathered in a time sequence.
- It is usually represented on a graph where the measure of time is expressed on the x-axis and what is to be measured is represented on the y-axis. It is also used for the visualization of trends and patterns. e.g seasonal changes in climate.
