Follow-up Question
Suppose you wish to conduct a test of the research hypothesis that the median of a population is greater than 78.
You randomly sample 15 measurements from the population and determine that 10 of them exceed 78. Set up and
conduct the appropriate test of hypothesis at the 0.10 level of significance. Be sure to specify all necessary
assumptions.
Find the p-value for this nypothesis test.
p-value = 0.150 (Round to three decimal places as needed.)
What is the correct conclusion for this hypothesis test?
A. Do not reject Ho. There is insufficient evidence to indicate the median is greater than 78 at α = 0.10.
B. Reject Ho. There is sufficient evidence to indicate the median is greater than 78 at α = 0.10.
C. Reject Ho. There is insufficient evidence to indicate the median is greater than 78 at x = 0.10.
D. Do not reject Ho. There is sufficient evidence to indicate the median is greater than 78 at x = 0.10.
Identify the necessary assumption(s). Select all that apply.
A. Assume that the sample is randomly selected
from a continuous probability distribution.
C. Assume that the probability distribution of the
sampled population is nonnormal.
E. Assume that the probability distribution of the
sampled population is approximately normal.
B. Assume that the sample size is less than 5% of
the entire population.
D. Assume that the probability distribution of the
sampled population is not skewed.
F. There are no necessary assumptions.
