Answer:
1.4 inches (1 decimal place)
Step-by-step explanation:
To calculate the mean you get the sum of all the terms required and divide by the number of terms you summed up.
All of the terms in the table sum up to 29/3. 29/3 divided by 7 (number of days in a week) = 1.3809..., which you can round to 1.4 inches
