Reconsider the fast-food restaurant visit discussed in chapter 1 (statistical quality control 10th Ed). What levels of quality would you consider acceptable for the family of four on each visit and annually? What probability of good quality on each meal component (assume 10 meal components in a typical restaurant meal) would be required in order to achieve these targets?
Added by Melissa G.
Step 1
First, we need to determine the acceptable level of quality for the family of four on each visit. Let's assume that an acceptable level of quality means that at least 90% of the meal components are of good quality. Since there are 10 meal components in a typical Show more…

In response to concerns about nutritional contents of fast foods, McDonald's announced that it would use a new cooking oil for its french fries that would decrease substantially trans fatty acid levels and increase the amount of more beneficial polyunsaturated fat. The company claimed that 97 out of 100 people cannot detect a difference in taste between the new and old oils. Assuming that this figure is correct (as a long-run proportion), what is the approximate probability that in a random sample of 1000 individuals who have purchased fries at McDonald's, (a) At least 40 can taste the difference between the two oils? (b) At most 5$\%$ can taste the difference between the two oils?
Continuous Random Variables and Probability Distributions
The Normal (Gaussian) Distribution
Eating at Fast Food Restaurants A survey was taken of 50 individuals. They were asked how many days per week they ate at a fast-food restaurant. Construct a frequency distribution using 8 classes $(0-7) .$ Based on the distribution, how often did most people eat at a fastfood restaurant? $$ \begin{array}{lllll} 1 & 3 & 4 & 0 & 4 \\ 5 & 2 & 2 & 3 & 1 \\ 2 & 2 & 2 & 2 & 2 \\ 2 & 2 & 2 & 2 & 3 \\ 2 & 2 & 5 & 2 & 4 \\ 2 & 4 & 5 & 2 & 1 \\ 4 & 1 & 3 & 2 & 2 \\ 2 & 0 & 7 & 2 & 3 \\ 2 & 2 & 2 & 5 & 2 \\ 3 & 3 & 4 & 1 & 3 \end{array} $$
Frequency Distributions and Graphs
Organizing Data
Use the data in the following table, which lists drive-thru order accuracy at popular fast food chains (data from a QSR Drive-Thru Study). Assume that orders are \mathrm{\{} \text { randomly selected from those included in the table. } If one order is selected, find the probability of getting an order from McDonald's or Wendy's or an order that is not accurate.
