Mean is the same as average - could you try working out the average number of electronic devices given the numbers as indicated in your question above?

3.5 but thts not an answer

shiraz14 · Answer

You're right - 3.5 is incorrect (it's a calculation error).
Try again. Average = Total number of electronic devices/total number of groups.

Also, where's the frequency table? I was assuming that the options were the frequencies - is this correct?

no

shiraz14 · Answer

so where's the frequency table? If 3.5 was the answer you found, you should still round this to the nearest whole number (i.e. 4) since your question specifically states so.
