1. The overall shape of this histogram is
A) roughly uniform B) roughly symmetric C) skewed right D) skewed left
2. Approximately how many students researched cars with prices around 10,000 dollars?
A) 60 B) 70 C) cannot be determined from the graph. D) 70%
3. The Inter Quartile Range is IQR = Q3 - Q1 . One rule of thumb for 'outliers' says that any data value below Q1 - 1.5 * IQR or above Q3 + 1.5 * IQR can be labelled an outlier. Use this rule to determine whether there are any outliers in the Price_Car data.
A) Because Q1 - 1.5*IQR comes out to be a negative number, the Price_Car data cannot have outliers. B) Because the maximum value is 99,000 and any value above 54,375 may be considered an outlier, the Price_Car data must have outliers. C) Because there are no large gaps in the histogram, the data must not have an outlier. D) Because the tallest column is around 15000, all prices between 0 and 30,000 must be considered outliers.
