can someone correct me please...

Find the mean. Round to the nearest tenth.

*its a table with 2colums and 5 rows:
*/* = this is used for separation of columns:
value / frequency

146/3
216/2
257/3
278/4
320/2

This is what i did i did a third column and whats in it is the value times frequency of each row....then i added them up and ended up with 3393 then divided the total amount of the third column with the total amount in column two of frequency which is 14.

so,

3393/14 = 242.35 so when i rounded it to the nearest tenth then it would be 242.40

correct, except for nitpick: If it is rounded to the nearest tenth, why did you list the hundredths digit?
