Problem 3. Frito-Way, a potato chip manufacturer, uses the following method to check for salt content of
their chips: every 40 minutes one bag of chips is taken from the conveyor and electronically analyzed for
sodium content. The value of the sodium content is then multiplied by a factor as indicated in the table
below to obtain a revised value:
Chip Type (Flavor) Factor
Plain
1
Sour Cream
0.94
Barbecue
0.85
Salt & Pepper
1.2
The target is to have a revised value greater than 170 mg/oz, but less than 185 mg/oz. To help FW, design
an app to look as in Figure 3 (only use the controls shown in the figure). The app will output the date and
time of the sample, as well as whether the sample's average sodium content is "within target", "below
target", or "above target" for the type of chip. For example, a sample of Barbecue chips with an average
sodium of 196 mg/oz will yield a revised value of 196 x 0.85 = 166.6 (lower than 170) and hence, will be
classified as "below target". Place a button to open the form.
