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.
B and C make sense to me.
Answer:
$6
Step-by-step explanation:
We have: The cost of a taxi ride is represented by the function c(m)=2m+4
Plug 1 mile into "m" of the function c(m)=2m+4
So, we have c (1) = 2 ˣ 1 + 4 = 6
Thus, The cost per mile of the cab is $6.
By definition, the sine of an angle is given by:
Where,
C.O: opposite leg
h: hypotenuse
The hypotenuse is given by:
So, replacing values we have:
Rewriting we have:
Answer:
the sine value of this function is:
