Answer:Mean = 258.44
Median=248
Mode=209&248
Mid-range=329.5
Step-by-step explanation:
Mean=
sum of all numbers/number of occurrence
(450 +243 +227 +248 +248 +291 +278 +228 +241 +209 +265+ 234 +209 +257 +252 +255)/16=258.44
Median= the middle number when arranged in accending or defending order=248
209 209 227 228 234 241 243 248 248 252 255 257 265 278 291 450
Since there 2 middle numbers (248 248) the median will be the mean of both which is (248+248)/2
Mode= highest occuring number
( since there 2 numbers occurring the most) this is a Bi-mode =209 and 248.
Mid range= (highest+ lowest)/2
(450+209)/2
=329.5
