The following dot plot represents the litter sizes of a random sample of labrador retrievers. Calculate the mean, median, and mode for this set of data.
Calculate the range, interquartile range, and mean absolute deviation (rounded to the nearest hundredth) for this set of data. For the mean absolute deviation, do not round the mean.
Make two inferences about the litter size of labrador retrievers.

1. The mean is 4, the median is 7, and the mode is 7

2. The Range is 6, the interquartile range is 6, and the mean absolute deviation is 6.5

3. 7 is the most common litter and 12 has 2 Labrador retrievers

Step-by-step explanation:

All I know is that the first part is correct but I am not sure for the rest hope it helped in some how.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
