Answer 1

Hello there.

1. Find the mean, median, and mode of the data set.
Time spent on Internet (min/day):
75, 38, 43, 120, 65, 48, 52

D) mean: 63, median: 52, no mode

Answer 2

1. The data are
75, 38, 43, 120, 65, 48, 52
Adding them and dividing by the number of data gives the mean which is 63.
Arranging them from lowest to highest and taking the middle data gives the median which is 52.
Since no data is repeated, this means that there is no mode.
The answer is
D) mean: 63, median: 52, no mode

2.The answer is
A) mean

3. The realistic data to represent the weight of books is
A) mean
