Answer: Craig's household use of water during the billing period = 129 CFC
Explanation:
Since we have given that
Craig's June water meter's previous reading =6372 CFC
Craig's water meter's present reading =6501 CFC
Craig's household use during the billing period =6501 -6372= 129 CFC

we are given

Firstly , we can distribute

now, we can combine like terms


now, we can solve for x
and we get

Answer:
Null hypothesis is: U1 - U2 ≤ 0
Alternative hypothesis is U1 - U2 > 0
Step-by-step explanation:
The question involves a comparison of the two types of training given to the salespeople. The requirement is to set up the hypothesis that type A training leads to higher mean weakly sales compared to type B training.
Let U1 = mean sales by type A trainees
Let U2 = mean sales by type B trainees
Therefore, the null hypothesis (H0) is: U1 - U2 ≤ 0
This implies that type A training does not result in higher mean weekly sales than type B training.
The alternative hypothesis (H1) is: U1 - U2 > 0
This implies that type A training indeed results in higher mean weekly sales than type B training.
