Solution:
n = 21
44th percentile is the value in the data which divides the data such that
P[X < P44 ] = 0.44 and P[X > P44] > 0.56
So
P44 is [(44/100)*21] th observation
The given data is already in the ascending order
So
P44 = 37.8 = 38
Answer :
P44 = 37.8

For each variable of interest, do the following: 1. Find the mean, five-number summary, range, variance, and standard deviation. Display these numbers in a format that is easy to understand. 2. For each variable of interest, use its five-number summary to construct a boxplot. Each boxplot must be constructed horizontally, and must be accompanied by a brief descriptive paragraph that assesses whether the data appear to be symmetrical, left-skewed, or right-skewed. Construct a 95% confidence interval for the mean μ...
