Answer:
The mean is 4.88 hours / day
Step-by-step explanation:
To calculate the mean we just add the values and divide by the number of items (in this case we add the hours and divide by the number of days)
so the equation would be

For table # 1:
x= 1 * 3.5 = 3.5
x = 2*3.5 = 7
x = 3*3.5 = 10.5
x = 4* 3.5 = 14
For table #2
x=1 * 3 = 3
x =2 * 3 = 6
x = 3*3 = 9
x = 4* 3 = 12
Hence, the data sets show multiplicative relationships:
For data set 1 is 3.5 times x, and in data set 2 y is 3 times x.
Answer:
