August 31, 2017

Question
a. Calculate the mean attitude score toward the Springdale Mall shopping area and compute the sample standard deviation. Does this area seem to be well regarded by the respondents?
b. In a two-tail test at the 0.10 level, compare the sample mean calculated in part (a) to the 3.0 “neutral” value. Use the null hypothesis and the alternative hypothesis .
c. Generate the 90% confidence interval for the population mean and use this interval in verifying the conclusion obtained in part (b).
d. What is the p-value associated with the hypothesis test?
e. Repeat parts (a) through (d) for the Downtown shopping area.
f. Repeat parts (a) through (d) for the West Mall shopping area.
2. If Springdale Mall offered exactly the same benefits as the other two shopping areas, we would expect exactly one-third of those who expressed an opinion to select it as the area best fitting the description for variable number 10 (“Easy to return/exchange goods”). In testing whether Springdale Mall differs significantly from this expected proportion, the null and alternative hypotheses will be . Carry out the following analyses for Springdale Mall:
a. Analyzing the data for variable 10, use the preceding null and alternative hypotheses in testing the null hypothesis at the 0.05 level.
b. Determine the p-value for the test conducted in part (a).
c. Repeat parts (a) and (b) for variables 11–17.
d. Based on the preceding analyses, identify the principal strengths and weaknesses exhibited by Springdale Mall.
