At a significant level of 0.05, is there a difference in the
distribution of the two groups? Use the Smirnov Test method to
test. Thank you :)

Consider these 15 scores as 15 scores of 15 students in a class
to answer the questions below:
What is the 15% trimmed mean of these 15 data points?
What is the sample of mean of these 15 data points?
What is the probability that a randomly chosen number among
these data points is between 95 & 100, exclusive of the
ends?
