can someone help me with this?

Acrylamide (a possible cancer-causing substance) forms in high-carbohydrate foods cooked at high temperatures and acrylamide levels can vary widely even within the same type of food. An article appearing in the journal Food Chemistry included the following acrylamide content (in nanograms/gram) for seven brands of biscuits.+ 498 192 327 155 326 245 270 (3) Calculate the mean acrylarnide level. (Round your answer to three decimal places.) ppb Calculate the seven deviations from the mean. (Round your answers to three decimal places.) Value (ppb) Deviation (ppb) 498 192 327 155 326 245 270 (b) Verify that, except for the effect of rounding, the sum of the deviations from the mean is equal to 0 for this data set. (If you rounded the sample mean or the deviations, your sum may not be exactly zero, but it should be close to zero if you have calculated the deviations correctly. Round your answer to three decimal places.) The sum of the deviations from the mean is ppb. (c) Calculate the variance and standard deviation (in ppb) for this data set. (Round your answers to three decimal places.) variance standard deviation ppb
