Question

Effects of herbicide treatment. What’s diffrent ?

I’m in meed of help on questions 5.1-5.3

ue tead sos bean RR+ is the roundup ready soybean in a field treated with roundup: a roundup ready soybean treated with conventional herbicide (not roundup); is conventional soybean treated with the same conventional herbicide as the RRS treatment. CN 1Effect of herbicide treatment on soybean yield in 1998, 1999, and 2000 at Crawfordsville IA Mean yield performance 1999 Herbicide treatment 1998-2000 1998 2000 (Bushels/acre) 48.7b 49.2 b 50.9 a 43.6 b 48.2 b 42.3b 47.2b 45.9a 50.8 a 52.4 b 50.3 с 55.7 a RRS CN Within columns, herbicide treatment mean yields followed by different letters are statistically different (Pc0.05) 5.1. What does it mean when treatments are statistically different (P<0.05)? 5.2. Name one statistical test that can be used to determine whether samples are different. 5.3. What conclusion would you draw from the above field trials? You also notice that your newly developed "Roundup Ready" (RR) soy plant appears to be shorter and a little "woodier" and tough than non-RoundupReady soy plants. Fluorescence microscopy and staining with toluidine blue indicated a higher content of lignin in the sclerenchyma cells surrounding the vascular bundle in all of the transgenic soybean plants than in their non-transformed counterparts. You chemically analyse the lignin content of the transgenic lines you generated and compare their lignin content with that of genetically identical "isolines" that haven't been transformed. The results are shown in table 2.

Answer 1

Solution:

5.1
The treatments are treated with a statistical test of comparison of means against the hypothesis that the mean of all the variable class is equal among the groups. This hypothesis is called the null hypothesis and the alternative hypothesis to this statistical study is that the mean of all the variable class is different. Hence, We conduct the statistical test on the data and find the p-value for the test. It is known that whenever the P-value is less than 0.05 (For 95% confidence level) the null hypothesis is rejected. Hence, when the null hypothesis is rejected we conclude that the mean of all the variable classes is statistically different. ( which alternate hypothesis states). Hence, this is the inference behind this statement that the means are statistically different.

5.2
We use 2 way ANOVA for this given data for comparison of means.

5.3
The conclusion can be drawn that there is a significant difference in the yield performance depending on the choice of the herbicide treatment used. hence, The Herbicide treatments will show varied results of performance for the crop production and have different efficiencies on the yield performance.
