For each data set provided, explain what the measured value
implies about the melting point technique used and the purity of
the acenallide Your explanation of the data must show an
understanding of the scientific principles of melting point data.
Hint: comparison against the known melting point is a very useful
starting point for your discussion of this data. The literature
melting point of acetanilide is 114.3
A. melting point 120-124
B.Melting point: 108.5-110.0 ºC
C Melting point: 105.0-113.5 ºC...

(a) This exercise will give an example of a connected
space which is
not locally connected. In the plane R2
, let X0 = [0, 1] × {0},
Y0 = {0} × [0, 1], and for each n ∈ N, let Yn = {1/n} × [0,1]. Let
Y = X0 ∪ (S∞
n=0 Yn). as a subspace of R

Prove that Y is connected but not locally connected. (Note

A data set includes data from student evaluations of courses.
The summary statistics are n = 84, x (x bar) = 4.16, s = 0.59. Use
a 0.05 significance level to test the claim that the population of
student course evaluations has a mean equal to 4.25. Assume that a
simple random sample has been selected. Identify the null and
alternative hypotheses, test statistic, P-value, and state the
final conclusion that addresses the original claim. Show your work.
