Soybeans are a valuable crop and some growers choose genetically modified soybea

Question

Soybeans are a valuable crop and some growers choose genetically modified soybean seeds that are herbicide tolerant (HT) so that they can use Roundup to reduce competition from weeds. Other growers choose non-genetically modified seeds that are not herbicide tolerant (NHT) because they are less expensive to purchase and weeds can be controlled using disking ( tilling between rows). Some researchers in North Dakota wanted to know if the herbicide tolerant seed was worth the higher price. They measured average number of bushels per acre for 100 herbicide tolerant fields and 80 non herbicide tolerant fields to see if yields different between seed types.

Explanation / Answer

a) independent samples

b) Is this a one tailed or two tailed test?

    Ans: Two tailed test

c) Identify the test you have chosen for the data?

ans: the two sample ttest

d)

Null Hypothesis: Their is no difference in the measured average number of bushels per acre for 100 herbicide tolerant fields and 80 non herbicide tolerant fields.

Alternative Hypothesis : Their is significant difference in the measured average number of bushels per acre for 100 herbicide tolerant fields and 80 non herbicide tolerant fields.
