Applying a level 200 corn seeds were divided equally into two groups. The treatment group was sprayed with a new type of fertilizer. The results showed that the mean change in the growth rate is 8 more points than the control group. Consider the significance level to be set at5% so results less than 5% can be considered statistically significant. Mean of treatment group is -7%. Determine the probability of the treatment groups mean being greater than the controls mean by 8 points or more. Answer the questions.
The significance level is set at 5% and the probability of the result is 1 5.9 5 3.6 or 2.6% which is the same as greater than less than the significance level. The result is inconclusive statistically significant not statistically significant
