we have the data set

768,769,814,895,901,913,937,963

so

Find out the mean

mean=(768+769+814+895+901+913+937+963)/8

mean=6,960/8

mean=870

Find out the median

768,769,814,895,901,913,937,963

median=(895+901)/2

median=898

Part a

$768 salary changes to $912

the new data set is

769,814,895,901,912,913,937,963

Find out the new mean

mean=(6,960-768+912)/8

mean=888

therefore

The new mean increases by $18

Part B

Find out the new median

769,814,895,901,912,913,937,963

median=(901+912)/2

median=906.5

therefore

It increases by $8.5
