Question
108 109 Next THREE questions are based on the following mployed adults in Indianapolis metropolitan area (IMA), the average commuting time to work was x 40.5 minutes, there enough evidence, at ?-0.05, to conclude that the average commuting time in IMA is less than the national 110 American workers spend an average of 46 minutes to and from work in a typical day. In a sample of n 104 112 with s 21.6 minutes. 114 average? To perform a hypothesis test, the null and alternative hypotheses for this test are: A B C D H1: ?Explanation / Answer
X?= 40.5
n= 104
s= 21.6
df= 104-1=103
claim u< 46 H1
opposite u ? 46 H0
H0: u= 46
H1: u< 46 left tail test
alpha= 0.05
Test Statictics
T= (X?-u)*sqrt(n)/s
=(40.5-46)*sqrt(104)/21.6
=-2.5967229
P-value= 0.005393799
rounded p-value=0.005
Decision making
P-value ? Alpha Reject H0
0.005 <0.05
there is enough evidence to support the claim that mean is less than 46.

Answers
