Answer 1

Answer:

1).

99% CI for mean difference= (0.5109, 6.0891).

2).

Type of variable: independent: categorical dependent: continuous

Type of question: difference

Basis of comparison: means

Ho: µ1 = µ2   H1: µ1 > µ2

α =0.01 one tail test ( upper tail test)

Two sample students unpaired t

P= 0.0016 compare p value with α =0.01

Reject H0. ( because P value < α).

There is sufficient evidence to conclude that the mean yield of the genetically modified variety is greater than that for the standard variety.
