The U.S. Food and Drug Administration (FDA) performed a study that compared the carbohydrate content (as a percentage of weight)

of several major brands of corn and potato chips. Fourteen brands of corn chips were sampled and 14 brands of potato chips were sampled. Data was collected and the following 95% confidence interval was computed for the difference in means. Intrepret the 95% confidence interval for the difference in the mean carbohydrate content between the Corn Chip and Potato Chip groups. The C.I. is: (27.292,39.836)

Answer:

95% confidence interval for the difference in the mean carbohydrate content between the corn chip and potato chip group is between a lower limit of 27.292 and an upper limit of 39.836.

Step-by-step explanation:

Confidence interval is given by mean +/- margin of error and is expressed by enclosing the lower and upper limits of the mean separated by a comma in parentheses.

95% confidence interval for the difference in mean carbohydrate content between the corn chip and potato chip groups is given as (27.292, 39.836). This means that the difference in mean carbohydrate content between the two chip groups is between 27.292 and 39.836.
