answer
B)0.66
Step-by-step explanation:
0.66 value of the correlation coefficient r of the data set
32.3cm (nearly 13 inches) (12.9 inches)
2.5cm = 1 inch. To figure out what 3 quarters ( 3/4 ) of an inch is, divide 2.5 by 4 then multiply by 3. ( 2.5/4 x3 ) This equals 1.9cm. There are 17 blocks so multiply 1.9 by 17. ( 1.9/17 = 32.3) 30 cm = 12 inches. 2.3 is 90% of 2.5, so add 0.9 to 12.

Answer:
D. Both distributions are skewed left, so the interquartile range is the best measure to compare variability.
Step-by-step explanation:
Plotting the data roughly shows that the data is skewed to the left. In other words, data is skewed negatively and that the long tail will be on the negative side of the peak.
In such a scenario, interquartile range is normally the best measure to compare variations of data.
Therefore, the last option is the best for the data provided.
