Answer:
There was no error
Step-by-step explanation:
There are two types of statistical errors, the type 1 error and the type 2 error. In this case we refute the null hypothesis when the hypothesis is, in fact, false, because the mean process is 9 days instead of 7. Therefore we made no errors.
If the null hypothesis were True, a type 1 error would have ocurred. If the null hypothesis were false and we didnt refute it, then a type 2 error would have ocurred.
Answer:
2400 gallons of water
Step-by-step explanation:
The new shower head releases 2 gallons per minute as compared to the old type.
each person spends an average of 8 minutes in shower per day. This means each person will use 8*2 number of gallons per day.
the number of persons in the family is 5.
if 1 person uses 8*2 gallons per day, 5 people will require 8*2*5
In a 30 days period the number of gallons used by the family will be
=8*2*5*30
=2400 gallons.
