From the question we are told that
The sample size is n = 15
The level of significance is 
The null hypothesis is 
The alternative hypothesis is 
Generally the degree of freedom is mathematically represented as

=> 
Generally the critical value of
at a degree of freedom of
is

Answer:
D
Step-by-step explanation:
yes it is found by multiplying phi with diameter of the circle
Solution
for this case we have the following function:

And we want to find the limiting size of the population, since this is a logistic function the loading or the limiting size needs to be:
34000
Answer:
the answer is -30.
Step-by-step explanation:
for each x-value, you will multiply it by -5 to get your y-value. i say this because if y-15 when x=-3, if you divide the x from y (so 15/-3) you get -5 which is the number in which y varies by. so you will take 6 and multiply it by -5 which gives you -30.
The solutions to f(x) = 64 is x = 7 and x = –7.
Solution:
Given data:
– – – – (1)
– – – – (2)
To find the solutions to f(x) = 64.
Equate equation (1) and (2), we get

Subtract 15 from both sides of the equation.



Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.
