Answer:

As both data distribution are not symmetric for both Coffee Shop A and Coffee Shop B. Therefore, it is appropriate to mention the centers of distribution in terms of median for both coffee shops.

Hence, option B should be correct option.

Step-by-step explanation:

Calculation for Coffee Shop A:

The data distribution for shop A:

$12, 52, 57, 33, 51, 15, 46, 45$

Arrange the data in ascending order.

$12, 15, 33, 45, 46, 51, 52, 57$

Mean for shop A:

$Mean=\frac{12+15+33+45+46+51+52+57}{8}=38.875$

$Median=\frac{(\frac{n}{2})th+(\frac{n}{2}+1)th}{2}=\frac{45+46}{2}=45.5$

As Mean and Median are not close. Hence, data distribution is not symmetric for Coffee Shop A.

Calculation for Coffee Shop B:

The data distribution for shop B:

$17, 16, 36, 35, 12, 9, 34, 15$

Arrange the data in ascending order.

$9, 12, 15, 16, 17, 34, 35, 36$

Mean for shop B:

$Mean=\frac{9+12+15+16+17+34+35+36}{8}=21.75$

$Median=\frac{(\frac{n}{2})th+(\frac{n}{2}+1)th}{2}=\frac{16+17}{2}=16.5$

As Mean and Median are not close. Hence, data distribution is not symmetric for Coffee Shop B.

As both data distribution are not symmetric for both Coffee Shop A and Coffee Shop B.

Therefore, it is appropriate to mention the centers of distribution in terms of median for both coffee shops.

Hence, option B should be correct option.

Convert 6 (whole number) 8/11 to a decimal

Vladimir79 [104]

Answer:

6.73

Step-by-step explanation:

6 (whole number) 8/11 is 6.7272 approximately 6.73 (3 s.f)

the 6 whole number gives the 6.

8/11 is 0 and using the whole long division method gives 0.7272...

cause when you add zero to 8 it becomes 80 and 11 goes into 80, 7 times giving 77.

subtracting 77 from 80 gives 3 adding 0 becomes 30 and 11 into 30 is 2 giving 22

I hope this helps
