Answer:
Step-by-step explanation:
The 95% confidence interval can be calculated as:
Where is the mean consumption of milk,
is the sample mean,
is the population standard deviation,
is the size of the sample,
is 5% and
is the z-value that let a probability of
on the right tail.
So, replacing by 3.4 liters,
by 1.3 liters, n by 650 and
by 1.96, we get that the 95% confidence interval is equal to:
Answer:
Sarah's age is 60 years
Step-by-step explanation:
<u><em>The correct question is:</em></u>
64 is 4 times the difference between Sarah's age, a, and 44. Assume Sarah is older than 44. Write an equation to determine Sarah's age
Let
a ----> Sarah's age
we know that
The difference of Sarah's age and 44, all multiplied by 4 is equal to 64
so
The linear equation that represent this problem is
Solve for a
Apply distributive property left side
Adds 176 both sides
Divide by 4 both sides
therefore
Sarah's age is 60 years
