Answer:
The 95% confidence interval for the population mean daily protein intake is between 69.97g and 84.03g.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 77 - 7.03 = 69.97g.
The upper end of the interval is the sample mean added to M. So it is 77 + 7.03 = 84.03g.
The 95% confidence interval for the population mean daily protein intake is between 69.97g and 84.03g.
Step-by-step explanation:
= 24 × 17 × 12
= 4,896 in³
= 12 × 10 × 4
= 480 in³
The volume of the figure
= 4,896 + 480
= 5,376 in³
One ton = 2000 lbs
Therefore, 1.5 tons = 3000 lbs
3000-300=2700lbs
Answer:
her average speed is 16 miles per hour
Step-by-step explanation:
do 48 divided by 3 = 16
Height = 19.75
diam = 19.75*1.4 =
