An agricultural products manufacturer's research and development division is testing a newly developed wheat fertilizer.

Wheat is planted in several test areas (plots), which are in a controlled environment. Each area is randomly assigned a specific quantity of the fertilizer: either no fertilizer, a small amount, or a large amount of fertilizer.

The amount of water and the temperature are carefully controlled at specified levels and monitored for each test area: each area is maintained at either 78 °F or 71 °F for the duration of the test. Each area is administered either 2, 4 or 8 litres of water per week.

After three months, the yield (i.e. the amount of wheat produced) for each group is measured and the results are compared

a)This testing procedure is an example of a:

A. completely randomized design experiment
B. randomized block design experiment
C. matched pairs experiment

b)The unit of this experiment is the:

A. fertilizer
B. wheat

c)The factors of this experiment are:

A. season
B. application of fertilizer
C. sunlight
D. temperature
E. water
F. time period

d)Identify the response in the experiment:

A. amount of fertilizer
B. yield

The production of agricultural products like wheat is one of the few examples of a perfectly competitive industry. In this question, we analyze results from a study released by the Pakistan Department of Agriculture about wheat production in the Pakistan. a. The average variable cost per acre planted with wheat was Rs.1070 per acre. Assuming a yield of 500 bushels per acre, calculate the average variable cost per bushel of wheat. b. The average price of wheat received by a...

As a chemist for an agricultural products company, you have just developed a new herbicide,"Herbigon," that you think has the potential to kill weeds effectively. A sparingly soluble salt, Herbigon is dissolved in 1 M acetic acid for technical reasons having to do with its production. You have determined that the solubility product Ksp of Herbigon is 9.50×10−6. Although the formula of this new chemical is a trade secret, it can be revealed that the formula for Herbigon is X-acetate...

The director of research and development is testing a new medicine. She wants to know if there is evidence at the 0.02 level that the medicine relieves pain in more than 394 seconds. For a sample of 68 patients, the mean time in which the medicine relieved pain was 398 seconds. Assume a population standard deviation of 21. Determine the P -value of the test statistic. Round your answer to 4 decimal places.
