A researcher looked at young people's Knowledge of the cost of weddings, where it's been found that many students' estimates of the cost of a wedding was less than the actual average. As a result of this finding, imagine you hypothesize that young people will underestimate the average cost of a wedding gown. To test this hypothesis, a group of college students are asked, "According to the Brides.com ( HYPERLINK "http://www.brides.com/" http://www.brides.com) 2009 American Wedding Survey, what is the average cost of a wedding gown?" The responses of some of the students in this class are summarized as:
N = 28 = 2432.14
s = 1643.18
-According to Brides.com, the average cost of a wedding gown was $1075. Therefore, in this study, how would the null and alternative hypotheses be stated?
A) H0: μ > 1075; H1: μ < 1075
B) H0: μ ≠ 1075; H1: μ = 1075
C) H0: μ = 1075; H1: μ ≠ 1075
D) H0: μ = 2432.14; H1: μ ≠ 2432.14
