Answer:
Average is less than 65, therefore, shop did not meet the target.
Step-by-step explanation:
The time series graph gives some information about the number of umbrellas sold in a shop in the first six months of 2015.
From the given graph it is clear that the number of umbrellas sold in Jan, Feb, Mar, Apr, May, June are 54, 84, 72, 94, 52, 26 respectively.
Average sales is
[tex]Average=\dfrac{\text{Sum of number of umbrellas sold in 6 months}}{6}[/tex]
[tex]Average=\dfrac{54+84+72+94+52+26}{6}[/tex]
[tex]Average=\dfrac{382}{6}[/tex]
[tex]Average=63.67<65[/tex]
Since, average is less than 65, therefore, shop did not meet the target.
From the time-series, it is found that since the mean is below 65, the shop did not meet the target.
The mean of data-set is the sum of all observations divided by the number of observations.
From the time-series, there are 6 observations: 55, 85, 72, 90, 52, 25.
Hence, the mean is:
[tex]M - \frac{55 + 85 + 72 + 90 + 52 + 25}{6} = 63.2[/tex]
Since the mean is below 65, the shop did not meet the target.
