If a data point is to be chosen at random from those points for which the monthly ice-cream consumption per person is greater than 0.4 pint, what is the probability that the average temperature corresponding to the data point chosen will be lower than 60℉?
Which of the following is closest to the range of the monthly ice-cream consumption per person, in pints, for the 27 months?
Approximately what is the highest average temperature among those temperatures for which the monthly ice-cream consumption per person is less than 0.3 pint?
Of the 27 data points, P is the point for which the ratio of the monthly ice-cream consumption per person, in pints, to the average temperature,in degrees Fahrenheit,is greatest. Which of the following is closest to the average temperature that corresponds to P?
If one item is to be randomly selected from the items whose manufacturing cost is greater than $140, what is the probability that the item selected will be one whose manufacturing time is greater than 60 minutes?
For each item, a manager calculates the ratio of the manufacturing cost to the manufacturing time. Which of the following is closest to the value of the greatest of these eleven ratios, in dollars per minute?
The manufacturing cost of the item that takes the most time to manufacture is approximately what percent greater than the cost of the item that takes the least time to manufacture?
$$°C =\frac{5}{9}(°F -32)$$

The formula above can be used to convert temperatures from degrees Fahrenheit(°F) to degrees Celsius (°C), where (°F is a certain temperature expressed in degrees Fahrenheit and °C is the same temperature expressed in degrees Celsius. What was the maximum temperature in Atlanta, in degrees Celsius, rounded to the nearest degree?
