The manager of a supermarket would like to know which of several quality problems to address a tool that would be most helpful would be a Pareto chart.
A Pareto chart is a form of a graph with both bars and a line graph, where the bars reflect individual values in descending order and the line the cumulative total. The chart is called after the Pareto principle, which takes its name from renowned Italian economist Vilfredo Pareto.
The Pareto chart's goal is to draw attention to the most significant among a group of (usually several) components. Pareto charts can be used in quality control to identify the flaws that need to be fixed first in order to see the biggest overall improvement.
It frequently reflects the most frequent causes of faults, the most prevalent kind of defect, the most common causes of customer complaints, and so forth. For each bar in the Pareto chart, Wilkinson (2006) developed a method that generates statistically based acceptability limits (akin to confidence intervals).

When the price floor is set above the equilibrium price, the quantity supplied exceeds the quantity demanded, creating an oversupply or surplus. When government laws regulate prices instead of letting market forces set prices, this is the equilibrium price affect quantity demanded and quantity supplied.
If demand does not change, there is an inverse relationship between supply and price of goods and services. When the supply of goods and services increases at the same demand, prices tend to fall resulting in lower equilibrium prices and higher equilibrium quantities of goods and services.
Setting the price cap below the equilibrium price causes demand to exceed supply, resulting in overdemand or shortage. A floor price prevents the price from falling below a certain level.

Answer:
Answer for the question:
Bighorn sheep are beautiful wild animals found throughout the western United States. Let x be the age of a bighorn sheep (in years), and let y be the mortality rate (percent that die) for this age group. For example, x = 1, y = 14 means that 14% of the bighorn sheep between 1 and 2 years old died. A random sample of Arizona bighorn sheep gave the following information:x 1 2 3 4 5y 14 18.9 14.4 19.6 20.0 (a) Draw a scatter diagram. (3 points)(b) Find the equation of the least-squares line, and plot the line on the scatter diagram of part (a). (3 points)(c) Find the correlation coefficient r. Find the coefficient of determination . What percentage of variation in y is explained by the variation in x and the least squares model? (4 points)
