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.

where is the dot plot and the data

calculate the mean, median, and mode for this set of data 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. 3. make two inferences about the litter size of labrador retrievers.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
