Answer 1

The IQR goes from= 5.5 to 6.5

IQR= 6.5 - 5.5 = 1

The 15^th percentile is = 5.5

The 85^th percentile is = 6.5

The median is = 6

The empirical probability (use the data!) that a randomly chosen pinkie length is more than 6.5 cm = 6 instances of 6.5 out of 30 observations = 6/30 = 0.2

Explain the meaning of the 15^th percentile of this data.= It means 15% of observations are lesser than 15th percentile value if observations are arranged in ascending order. Similarly, 90th percentile means 90% of observations are lesser than the 90th percentile value f observations are arranged in increasing order.
