Question
The problem: (data are in the Minitab file eggs and SDA).According to new research, fish oil, has been found to possibly induce an effect of increasing ovulation in rats . This is possibly accomplished through an increase in the number of eggs produced and released during ovulation. Since some women show an allergy to fish oil, we are hoping to show that a substitute known as steriodonic acid (SDA) may induce the same effect. The data are number of eggs produced, per female, for rats ingesting fish oil and rats ingesting a high dose of SDA. The researchers would be pleased if the SDA egg-production was not lower than the fish oil egg production, so they phrased their research question as: Is there any evidence that SDA shows less production than fish oil?
the answer is
Difference = mu (SDA) - mu (oil)
Estimate for difference: 1.79
95% upper bound for difference: 4.33
T-Test of difference = 0 (vs <): T-Value = 1.26 P-Value = 0.884 DF = 12
but the question is
• An answer taken back to the language of the problem (for instance, don’t just report a p-value for a test; say what the results mean to the biologist).
Explanation / Answer
We can conclude by using P-Value: Here the P-value is 0.884, which is more than the level of significant 0.05 So we fail to reject Null Hypothesis. So we can conclude according to the problem(data) There is statistically insufficient evidence to conclude that SDA shows less production than fish oil at 5% level of significant.Related Questions
