We suspect the overall mean monthly rent of apartments in Shadyside is higher than in Oakland, so we survey a random sample of O
akland apartments, and a random sample of Shadyside apartments. 1. Which of the following is the most appropriate statistical test to use to determine if the overall mean monthly rent of apartments in Shadyside is higher than in Oakland?
a. Chi-squared test for independence
b. Inference for regression
c. Matched pairs t-test
d. ANOVA
e. Two-sample t-test
This is simply because you only have interval level of measure and you are comparing two populations.
Moreso, this hypothesis test is used to determine questions related to the mean in situations where data is collected from two random data samples. The two sample T-test is often used for evaluating the means of two variables or distinct groups, providing information as to whether the means between the two populations differs. It also can be used to compare the responses of males and females who have each received different treatment within an experiment.
The answer is x=-5.5 . 2x-3 = 4x+8 . subtract 2x from both sides and then subtract 8 from both sides and get -11=2x . then divide both sides by 2 to get . -5.5=x
