So the formula for this is for every inch of width, you multiply by 2 to get the length.
Here, I made a table for it.
2×2=4
4×2=8
7×2=14
8×2=16 or 16÷2=8

Answer:
The calcium level that is the borderline between low calcium levels and those not considered low is
Step-by-step explanation:
From the question we are told that
The mean is
The standard deviation
The proportion of the population with low calcium level is 5% = 0.05
Let X be a X random calcium level
Now the P(X < c) = 0.05
Here P denotes probability
c is population with calcium level at the borderline
Since the calcium level is normally distributed the z-value is evaluated as
The critical value for 0.05 from the standard normal distribution table is
=>
substituting values
