Statistics help finding out the answer to this question very desperate?
The Damon family owns a large grape vineyard in western New York along Lake Erie. The grapevines must be sprayed at the beginning of the growing season to protect against various insects and diseases. Two new insecticides have just been marketed: Pernod 5 and Action. To test their effectiveness, three long rows were selected and sprayed with Pernod 5, and three others were sprayed with Action. When the grapes ripened, 400 of the vines treated with Pernod 5 were checked for infestation. Likewise, a sample of 400 vines sprayed with Action were checked. The results are: Insecticide Number of Pernod 5 400 27 Action 400 40 37 minutes ago - 4 days left to answer. Additional Details At the .05 significance level, can we conclude that there is a difference in the proportion of vines infested using Pernod 5 as opposed to Action? Hint: For the calculations, assume the Pernod as the first sample. (1) State the decision rule. (Negative amounts should be indicated by a minus sign. Do not round the intermediate values.

What is the best course of action 24 hours before an exam?
1. Don't forget to be human:Make sure you get at least 4 hours of sleep (assuming you got 8-10 the night before). Eat at least 1 full meal and have a snack of fruit, nuts, and chocolate. Drink at least 3 glasses of water throughout the day.2. Do what you will be doing during the exam:Test yourself with practice problems. Don't waste time reading! If the exam is memorization based use flashcards to test yourself. If you will be writing (problem sets, code, essay questions) then answer some sample questions in writing. The most important part is to not use an answer key--you want to be able to keep track of what you do and do not know.3. Give yourself a grace period:I always finish studying 2 hours before the exam. This is a time to shower, collect myself, sharpen my pencils, take a 40-minute power nap if I need, stretch, calm myself, pump myself up..etc. Then when my bag is packed and I'm ready to go, if I have extra time I will continue to quiz myself.
Why do the BUET admission test questions never get leaked?
It is because of the way and timing in which the question papers are prepared.The evening before the exam day, the teachers from the department, which have been assigned to prepare this year's admission question paper, gather in a round table and start discussing and making the question paper. The question paper is made by the night.This paper is then printed early in the morning, just before the exam, at the BUET press. Hence, the exam sheets are usually pretty warm when served.It is impossible to leak the question papers to the general public in such a short fram of time between making and exam time. The teachers are very honest and concerned about the prestige of BUET so there can be no leak during the question setting process. The only other possible leak is when the papers are in the hands of the staff who print it but again 2–3 hours to leak is a very short time frame.Hence, the reason why BUET admission exam papers never get leaked.

False positive on random drug test for employer resulted in my termination. What action should I take?
Did you inform your employer that you are willing to pay the $150 to have the sample tested again? I would if I were you. Also, you may want to submit another sample and have it cross-checked with the original sample to make sure that the sample they possess is actually your urine and not someone else'. Just stay calm and explain to them that you are willing to do whatever it takes to prove your innocence. Edit: If they won't let you submit another sample for cross-checking, get a lawyer and force them to do so. You have a right to prove that their evidence is correct. They have made this situation a legal matter by refusing to prove the sample is yours.
