Answer:
The correct options are 2 and 3.
Step-by-step explanation:
In the given graph y-axis represents the atmospheric pressure, in pounds per square inch and x-axis represents altitude in miles above sea level.
From the given graph it is noticed that as altitude (value of x) increases, the atmospheric pressure (value of y) decreases and as altitude (value of x) decreases, the atmospheric pressure (value of y) increases.
At sea level, the value of x is 0.
The y-intercept of the graph is 14.
Therefore The atmospheric pressure is at sea level. Option 2 is correct.
As the altitude (value of x) approaches sea level (x=0), the atmospheric pressure increases.
Therefore the correct options are 2 and 3.

Answer:
You would expect 807 babies to weigh between 3 and 6 pounds.
Step-by-step explanation:
We are given that
Mean,pounds
Standard deviation,pounds
n=1500
We have to find how many would you expect to weigh between 3 and 6 pounds.
The weights for newborn babies is approximately normally distributed.
Now,
Number of newborn babies expect to weigh between 3 and 6 pounds
