CHEM 120 Quiz 1 (Version 1), CHEM 120: Introduction to General, Organic & Biological Chemistry with Lab, Verified and Correct Answers, Chamberlain College of Nursing.
1. Question : (TCO 1) You have been growing the same variety of corn for over
5 years. In the past two years, you have noticed that the yield has
decreased by 10% each year. You grow corn on 10 acres of land
and your yield should be 1,000 bushels per acre. Growing
conditions have been consistent for the past 5 years. You want to
identify another variety of corn that will produce 1,000 bushels per
acre. You currently grow Variety ZQB. You want to test two new
varieties, CAQ and TWX. You hypothesize that CAQ will produce
1,000 bushels per acre. Design an experiment to test this
hypothesis. Include your control(s) (2 pts) and your experimental
design (4 pts). Describe the experimental results that would support
your hypothesis. (2 pts) Be specific.
Student Answer: Fist I need to identify the question and decide which variety of corn
that will produce 1,000 bushels per acre. My hypothesis would be
that CAQ will produce 1,000 bushels per acre. My control group
would be the variety that I am currently growing ZQB. ZQB which
has produced 1,000 bushels per acre for a period of 5 years. To
conduct the Experiment I will use 6 acres of land, plant CAQ
variety on 3 and TWX variety on the other 3 acres on same day.
Procedure: I will water all 10 acres of land at the same time every
day. Each section of land will be fertilized land on same day. I will
then conduct observations over the next 2 years and document
accordingly. Post the second year I will take inventory of each
variety of bushels and calculate an average for each acre. ZQB-
produced 900 bushels per acre for year 1 ZQB- produced 850
bushels per acre for year 2. This averages to 875 bushels per acre
per year. CAQ- produced 900 bushels per acre for year 1 CAQ-
produced 1400 bushels per acre for year 2. This averages to 1150
bushels per acre per yea.r TWX- produced 650 bushels per acre for
year 1 TWX- produced 750 bushels per acre for year 2. The average
of both years is 700 bushels per acre per year. Just by looking at the
numbers there is a substantial distance between the averages of
bushels per acre per year. CAQ averaged 1150 bushels per each
acre per year, which exceeded my hypothesis. In comparison to the
average of TWX 700 and ZQB 875 bushels per acre per year.
