We test if the mean rent of all downtown Pittsburgh one bedroom apartments is different from the mean rent of all non-downtown one bedroom apartments by examining a random sample of downtown one-bedroom apartments and a random sample of non-downtown one-bedroom apartments.
A) One-way Analysis of Variance (ANOVA)
B) paired T-test with a two sided alternative
C) Regression
D) two sample proportion with a two sided alternative
E) T-test about a mean with a two sided alternative
F) Chi-square test of independence
G) two sample T-test with a two sided alternative
Determine the bounds on the p-value that would be used in testing each of the following null hypotheses using the p-value approach.
Explain the bias and sampling error
H0: pi1- pi2 .01 at alpha =.05 where p1=.08, p2=.035, n1 = 200, n2 = 400. Indicate which test you are performing; show the test statistic and the critical values and mention whether one-tailed or two-tailed.
