Chapter 17, Problem 17.18P

(a)

Interpretation Introduction

Interpretation:

Graph has to be prepared to determine concentration of ascorbic acid in the orange juice.

Concept Introduction:

Formula to calculate uncertainty in x-intercept is as follows:

  $\text{Standard deviation in x-intercept}=\frac{s_y}{\left|m\right|}\sqrt{\frac{1}{n}+\frac{{\left(\overline{y}\right)}^2}{m^2{\displaystyle \sum \left(x_i-\overline{x}\right)}}}$

(b)

Interpretation Introduction

Interpretation:

Concentration of ascorbic acid in the orange juice along with principal uncertainty has to be estimated.

Concept Introduction:

Formula to calculate uncertainty in x-intercept is as follows:

  $\text{Standard deviation in x-intercept}=\frac{s_y}{\left|m\right|}\sqrt{\frac{1}{n}+\frac{{\left(\overline{y}\right)}^2}{m^2{\displaystyle \sum \left(x_i-\overline{x}\right)}}}$
