The data set below has an outlier 2,10,10,11,11.12,12,12,13,14,14
which value is changed the most by removing the outlier

Mean

Step-by-step explanation:

The mean with the outlier is

(2+10+10+11+11+12+12+12+13+14+14)/11  = 11

The mean without the outlier is

(10+10+11+11+12+12+12+13+14+14)/10  = 11.9

The median is the middle number

With the 2 it is 12

Without the 2 it is 12

Mode is most often

With the 2 it is 12

Without the 2 it is 12

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
