the number changes by the degree so you need to multiply it.
The cistern is losing approximately 3.963 gallons of water per hour.
<u><em>Explanation</em></u>
A cistern is leaking 0.25 liters of water per minute.
<u>We know, 1 gallon = 3.785 liters</u>
So, 0.25 liters = gallons
That means, the cistern is losing 0.06605....gallons of water per minute.
So, the amount of water losing in 1 hour or 60 minutes <em>(Approximately)</em>
Answer:
3.06
Step-by-step explanation:
The correct answer is - 3.06
Reason -
For sample A :
mean, = 8.05
Standard deviation, = 1.36
Size, = 50
For sample B :
mean, = 7.26
Standard deviation, = 1.06
Size, = 38
Now,
- = 8.05 - 7.26 = 0.79
Standard deviation error, SE = √(²/ + ²/) = 0.2580
Now,
Z-statistic = ( - )/ SE
= 0.79/0.2580
= 3.06
⇒Z-statistic = 3.06
