Suppose a certain drug test is 85% accurate, meaning that if a person is a user, the result is positive 85% of the time, and if

kakasveta [241]

Answer:

29.411 % of the result is true.

Step-by-step explanation:

This test's sensitivity is low.

Suppose we have 5 drug users and 85% of the test is accurate meaning that 5* 0.85= 4.25 people are drug users which is true.

But if work for the non users than 5% people being drug users means 95 people are non drug users out of the hundred.

And 85 % accuracy would give 95* 0.85= 80.75 which is very high.

And out of the 80.75 * 15%= 12.11 only 12 are positive .

The results give us 5 out of 17 true possibilities

or 5/17 *100= 29.411 % of the result is true.

rewona [7]

Answer:

The population growth is 6.26 per square mile per year

Step-by-step explanation:

We are given

he US Census found at the population per square mile in the state rose from 128.7 to 191.3 during the last 10 years

So,

Initial population =128.7

Final Population =191.3

Total time =10 years

now, we can find population grow per year

$=\frac{final-initial}{T}$

now, we can plug values

$=\frac{191.3-128.7}{10}$

$=6.26$

So,

The population growth is 6.26 per square mile per year
