Q1) According to American Express, it is hypothesized that average American has travelled to 8.4 states. WGN-TV felt this information was wrong. They did the survey of 22 Chicago area residents and found that they had travelled to the average of 6.5 states. Assume standard deviation for this problem was 1.1. Do 1-sample t-test to see if people in Chicago have travelled to fewer states than people nationwide. Utilize the 10% (.10) level of significance.

From information above, recognize these variables and their values:

X bar= ____________ µ= ____________ SD=____________

N = ____________ df= ____________ α= ____________

T= ____________ ... Use your table to find a critical value for "t".

T= ____________ ... Compute a test value for "t".

YES - NO (circle one) Do Chicagoans travel to significantly fewer states than people nationwide?

FORMULAE:

a) T = Mean Score (x bar) - Hypothesized value of population mean (µ) / SEM

b) SEM = SD/√n

c) df = n -1
