Scientists proposed the hypothesis: Consumption of Omega-3 fatty acid can reduce the size of cancerous tumors. the following hyp
othesis was tested. a sample of 500 rats with tumors was collected. within this sample size, 250 rats were feed with omega-3 (group 1) while the raining 250 rats were not (group 2). after one month of periodically feeding group 1 with omega-3 fatty acid, rat autospies were taken for both groups. the average changes of tumor size were measured and recorded. p value was .04. average change of tumor size group 1 -.124g group 2 -.012g. based on the results from the experiments, which of the following is the best conclusion?a. Consumption of Omega-3 fatty acid decreases the size of previous cancerous tumors with statistical significance. Correctb. Consumption of Omega-3 fatty acid has no effect on decreasing the size of previous cancerous tumors.c. Absence of Omega-3 fatty acid in the diet directly decreases the size of previous cancerous tumors.d. Absence of Omega-3 fatty acid in the diet decreases the size of previous cancerous tumors with statistical significance.e. Consumption of Omega-3 fatty acid directly decreases the size of previous cancerous tumors.
In a laboratory test such as this, when you obtain a p Value of less than 0.5 you conclude that there is a significant difference between the treatment and the control and thus you reject the null hypothesis of no difference. Therefore, with a p Value of 4 and observing that the rats that received Omega 3 had a bigger reduction in their cancerous tumors, we conclude that the treatment with Omega 3 decreased the size of previous cancerous tumors and that this effect was statistically significant.
Answer: They can have a positive impact on how the kids are eating. Maybe a kid don't get fed at home well the nutritionist will help he/she to get the food they need.
