What type of study was used for this investigation? Explain.
The mode of study in this case was on estimation. In this regard, the study seeks to establish certain facts through the method of estimation whereby the study seeks to come up with certain intervals of confidence and the limits in which they lie between (Spiegel & Stephens, 1999).
What would be the appropriate measure of association for this study?
The Pearsons correlation coefficient could be the best methods of association to be used in this case as it will help establish the correlation existing between the food items in the study. In this case, it will be easier to establish if the items in the study are positively or negatively correlated (Arlington, 2000).
Calculate the food-specific attack rates and calculate the measure of association between illness and each food item.
(21+23+27)/ (8+6+2) 71: 16
(81+76+76)/3=77/2/3 Prime Rib: 1.4 < 77.6> 65.7 Baked Potato 1.6 <77.6>218.5
Green Salad .10 -<77.6>42.9
What does a confidence interval mean, and which 95% confidence intervals are statistically significant?
Confidence intervals are very significant as they provide a way through which unknown parameters can be estimated in line with two values which are referred to as the confidence limits. Therefore, the parameter will always lie in between the limits at a certain confidence level. The baked potato interval is more significant as it provides a lower a highest limit in which the confidence interval exists.
What do the results indicate regarding the likely source of exposure?
The results indicate on the odds of exposure are among the food item in the study in comparison to the diseases that are associated as well. In this case, the r...
