Question

the dot - plot shows the weights, to the nearest quarter kilogram, of 20 newborns. describe the distribution of the weights. shape: the distribution of weights is blank. center: the median of the weights is blank kilograms. spread: the range of the weights is blank kilograms.

Explanation:

Step1: Determine shape

The dot - plot is symmetric around the middle value, so the shape is symmetric.

Step2: Find median

There are 20 data points. The median is the average of the 10th and 11th ordered data points. Counting the dots, the 10th and 11th values fall at 3.25 kg, so the median is 3.25 kg.

Step3: Calculate range

The smallest value is 2.5 kg and the largest value is 4 kg. Range = largest - smallest = 4 - 2.5 = 1.5 kg.

Step4: Check for outliers

There are no data points that are far away from the rest of the data, so there are no outliers.

Answer:

Shape: Symmetric
Center: 3.25
Spread: 1.5
Outliers: None
