Answer:
0.8808
Step-by-step explanation:
The objective is to calculate the probability of:
P(-1.20 ≤ z ≤ 2.64)
i.e. the probability that is the area between two z-values.
Thus;
P(-1.20 ≤ z ≤ 2.64) = P(z ≤ 2.64) - P( z ≤ 1.20)
From z table;
P(-1.20 ≤ z ≤ 2.64) = 0.9959 - 0.1151
P(-1.20 ≤ z ≤ 2.64) = 0.8808
We can see the shaded area under the standard normal curve from the image attached below.
Answer:
The Population Density is .
Step-by-step explanation:
Given,
Total number of People = 900,000
Total Land Area = 1800 sq. mi.
Solution,
For calculating the population density, we have to divide the total number of people by the area of the land.
This can be framed in equation form'
Now putting the given values, we get;
Hence The Population Density is .
