An agricultural research company has developed two new types of soy bean seeds, call thern "seed A" and "seed B". A study is conducted to deterrnine
which will produce a higher mean yield. To test the two types of seed, 20 similar plots of land were randornly placed into one of two groups. One group of
- ten plots was planted with "seed A", while the other ten plots were planted with "seed B". The yleld of each field, in bushels per acre, was recorded in the
table below.
Seed A 105 112 109 108 119 95 112 101 88 99
Seed B 97 94 102 105 84 100 87 91 103 88
1. Conduct a hypothesis test at a 0.05 level of significance to determine if the two types of soy beans produce different mean ylelds.
The test statistic is
The p-value is
Is there sufficient evidence to support the claim that mean ylelds are different?
A. No
B. Yes
2. Construct a 95% confidence interval for the mean of the differences. Hint: with the data in your lists, use the two-Independent sample t-INTERVAL
option on your calculator.
