Question

How do you expect the rank sum for sample A to compare to the rank sum for sample B if the median of distribution A is to the right of the median of distribution B? Explain your answer.

Answer #1

**Here' the answer to the question with full concept.
Please don't hesitate to give a "thumbs up" in case you're
satisfied with the answer**

Suppose that H1 : A>B is true:

**This results in sample A containing more of the larger
ranks. i.e. Rank sums of sample A will be higher than that of
sample B**

Evidence against H0 which confirms H1 : A>B is thus provided by an observed rank sum wA which is unusually large according to the distribution of rank sums when H0 is true.

Thus the P-value for the test is (H1 : A>B)

P-value = pr(WA ≥ wA), where the probability is calculated using the distribution that WA would have if H0 was true

observations with extreme/outlying values to decrease, stay the
same, or increase? Explain briefly.
b) Do you expect the range of sample values to decrease, stay
the same, or increase? Explain briefly.
c) Do you expect the sampling error to decrease, stay the same,
or increase? Explain briefly.

You must select a high
stiffness polymer. How do you expect the tensile modulus of the
following polymers compare:
1) Atactic PVC having
an average molecular weight of 500,000 g/mol
2) Isotactic PVC
having an average molecular weight of 500,000 g/mol
a) 2 will have a greater tensile modulus than 1
b) 1 will have a greater tensile modulus than 2
c) They exhibit about the same tensile modulus
