Answer:
D.
Step-by-step explanation:
The data is symmetric for Shop A but not for Shop B ( note the values 10 and 11 for Shop B which are a lot lower than the other values).
Mean for Shop A and Median for Shop B.
Answer:
The correct option is B.
Step-by-step explanation:
The number of lattes sold daily by two coffee shops is shown in the table.
The data set for shop A is
55, 52, 56, 48, 57, 30, 45, 41
Arrange the data in ascending order.
30, 41, 45, 48, 52, 55, 56, 57
Mean of shop A is
[tex]Mean=\frac{\sum x}{n}=\frac{30+41+45+48+52+55+56+57}{8}=48[/tex]
[tex]Median=\frac{(\frac{n}{2})th+(\frac{n}{2}+1)th}{2}=\frac{48+52}{2}=50[/tex]
The data set for shop B is
45, 42, 57, 48, 11, 10, 46, 43
Arrange the data in ascending order.
10, 11, 42, 43, 45, 46, 48, 57
Mean of shop A is
[tex]Mean=\frac{\sum x}{n}=\frac{10+11+42+43+45+46+48+57}{8}=37.75[/tex]
[tex]Median=\frac{(\frac{n}{2})th+(\frac{n}{2}+1)th}{2}=\frac{43+45}{2}=44[/tex]
Both data distribution are not symmetric, so it is better to describe the centers of distribution in terms of median for both coffee shops. Therefore the correct option is B.
