Answer: The critical value of the test is 2.807.
Step-by-step explanation:
Since we have given that
n = 24
So, the degree of freedom v = n-1 = 24 - 1=23
Since, n>30, so we will use 't-test'.
Here, α = 0.01
so, According to t-table, we get that
If we take α, then we are taking about two tail test.
If we take then we are talking about one tail test.
But in both the cases, the result will be same.
Hence, the critical value of the test is 2.807.
Answer:
Step-by-step explanation:
The population at various days is as follows since population triples every 3 days
<u>Day</u> <u>Population</u>
0 10
3 30
6 90
9 270
.... ......
This can be modeled by the general equation
where
is the population after t days
is the population at start (10)
is the rate at which population changes ie 3
is the number days from start
is the number of days at which the population triples(here k =3 days)
We can check this by plugging in values for each of the variables
At day 0, population = 10(3)⁰ = 10. 1 = 10
Similarly populations for days 3, 6, 9 are:
