Chemistry In an analysis of the content of carbohydrate present in a glycoprotein, the following results were found: 12.6, 11.9, 13.0, 12.7 and 12.5 g of carbohydrate per 100 g of protein. Taking into account that σ is unknown, the confidence interval for the average value at a 90% confidence level of the carbohydrate content is: Select one:to. 12.5 ± 0.4b. 12.5 ± 0.2c. 12.5 ± 0.5d. 12.5 ± 0.3

In a particular trial, a student got a value for R of 0.085. Calculate the percent deviation of this result. Enter a number without the % sign. The percent deviation should be reported as a positive value. (R accepted 0.082006)

Two-Step Algebra a = -bc+d Use the References to access important values if needed for this question. In order to solve the equation above for c, you must: Step One Add the same expression to each side of the equation to leave the term that includes the variable by itself on the right-hand side of the expression: +a = -bc+d
