For 2,000 mice living in a field,  the per capita growth rate  is mathematically given as
NT=0.4
<h3>What is the per capita growth rate (rmax) of mice over a month?</h3>
Generally,  the birth and death rate  is mathematically given as
BT=1000/2000
BT=0.5
Where
DT=200/2000
DT=0.1
In conclusion, per capita growth rate
NT=0.5-0.1
NT=0.4

Answer:
The test statistic for this hypothesis test is - 3.68.
Explanation:
A test statistic is a random variable that is calculated from sample data and used in a hypothesis test. You can use test statistics to determine whether to reject the null hypothesis. The test statistic compares your data with what is expected under the null hypothesis.
Sample proportion = 38/50 
= 0.76
Hence,
Test statistic

= 3.68
 
        
             
        
        
        
D= m/v
solve this formula to find v 
by solving we get,
v = m/D
v = 13/19.3
v = 0.67 cm^3
