Answer:
C
Step-by-step explanation:
Solution:-
- An experiment on the efficacy of spraying malathion on oats to control the growth cereal leaf beetle.
- A sample of n = 10 farms was taken at random. Each farm was either subjected to control group ( no spray ) or the treatment group ( spray ).
- Power ( β ) is the probability of rejecting the null hypothesis when, in fact, it is false. I.e the test statistics lie in the rejection region or the benefit of adding malathion is proven in-effective when in fact it is in-effective.
- Power is the probability of avoiding a ( Type II error ). Mathematically expressed as:
Type II Error = 1 - β
- Power is the probability of making a correct decision (to reject the null hypothesis) when the null hypothesis is false.
- The probability that a test of significance will pick up on an effect that is present.
Hence,
Answer: It is the ability to detect the effectiveness of malathion when in fact it is effective.
Answer:
9a+6b
Step-by-step explanation:
4a+7b+5a-b
First figure out the a's 4a + 5a = 9a
Then do b's (Remember, if there is no number by the letter then it is 1)
7b - 1b = 6b
So for this to be simplified the answer is 9a+6b
Answer:
by getting more attention on the app and there numbers get higher
Step-by-step explanation:
S(8)=3500(1+(.047/4))^32
S(8)=$5086.40 in the account after 8 years.
a)The relative growth rate is .25, or 25%
b)at t=0, the population is 955e^.25(0)=955
c)at t=5; the population is 955*e^.25(5)=955*3.49=3333.28 bacterium.
Answer:
Skewed to the left.
Step-by-step explanation:
The left side of the graph is at 2 and is 4 units from the middle at 6. The right side of the graph is at 9 and is 3 units from the middle. As such the graph is skewed left since it is a greater distance from the left to the center.
