.....child's household income level growing up and how they spend their money when they become adults. Essentially, you want to know if there is any association between childhood wealth and spending in their later years asadults -- not only in the sample but also in the larger population from which the sample was drawn.THIS DATA IS COMPLETELY MADE-UP. Below is the resulting contingency table with the actual frequencies.

Childhood Wealth Totals Spending in Adulthood Grew up 'poor' Grew up 'rich' 1=Frugal spender fe11=_____ fe12=_____ 2=Average spender fe21=_____ fe22=_____ 3=Big spender fe31=_____ fe32=_____ Totals Compute the expected frequencies (fe) for the table above. YOU MUST SHOW YOUR WORK. Formula; Eij = Ti * Tj /N fe11 = 65*67/140 = 31.11 fe12 = 65*73/140 = 33.89 fe21 = 45*67/140 = 21.54 fe22 = 45*73/140 = 23.46 fe31 = 30*67/140 = 14.36 fe32 = 30*73/140 = 15.64 2. State the null hypothesis and the research hypothesis. H0: There exists no association between childhood wealth, and spending in their later years H1: There is an association between childhood wealth, and spending in their later years 3.

When I make my final conclusion, I want to be 99% confident, therefore my p-value must be based on a significance level of: a. 0.1 b.0.5 c. 0.01 (explanation: confidence level = 1 -- significance level) d. 0.05 4. If the p-value I calculate is less than the significance level.
