Find the mean absolute deviation to the nearest cent. Explain what this value represents.
emmasim [6.3K]

Answer:

134.38

This value represents 134.38

Step-by-step explanation:

Find the mean.

950+620+545+810+775+1120+905+775=6500

6500/8=812.5

Subtract the mean of numbers.

950-812.5=137.5

812.5-620=192.5

812.5-545=267.5

812.5-810=2.5

812.5-775=37.5

1120-812.5=307.5

905-812.5=92.5

812.5-775=37.5

Find the mean.

137.5+192.5+267.5+2.5+37.5+307.5+92.5+37.5=1075

1075/8≈134.38

This means that 134.38 is $134.38
