Answer:
15595 bacteria will be present after 13 hours.
Step-by-step explanation:
Continuous population growth:
The continuous population growth model, for the population after t hours, is given by:
In which P(0) is the initial population and r is the growth rate.
Started with 5000 bacteria
This means that
So
After three hours it grew 6500 bacteria:
This means that . We use this to find r.
So
How many bacteria will be present after 13 hours?
This is P(13). So
Rounding to the nearest whole number
15595 bacteria will be present after 13 hours.
Answer:
Z_{0.005}>Z H₀ is wrong and other is correct. IT means $35000 is not mean value.
Step-by-step explanation:
Two hypothesis:
H₀=$35,000
Hₐ≠$35,000
Test Formula:
Where:
X is the mean value=$37,900
u is the value with 0.01 significance=$35000
S is the standard deviation
n is the sample size
Z=1.507
Z with 0.01 significance:
0.01/2=0.005=0.05%
Degrees of freedom=14-1=13
From t distribution table at 0.05% and 13 dof:
=4.221
So
Z_{0.005}>Z H₀ is wrong and other is correct. IT means $35000 is not mean value.
