Apples lose 75% of their weight during drying. How many pounds of fresh apples do you need to pick in order to get 150 lb of dri
Anna35 [415]
Since apples lose 75% of their weight, that means 150 lbs = 25% of fresh apples. 25% = 1/4, so the equation is 150/(1/4) = 150*4 = 600 lbs

lesantik [10]

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.
