(a) Write the Claim mathematically and identify Ho and Ha
(b) Find the critical value(s) and identify the rejection region(s)
(c) Find the Standardized test statistics.
(d) Decide whether to reject or fail to reject the null hypothesis
In a sample of 1788 of home buyers, you find that 637 home buyers found their real estate agents through a friend. At 0.08, can you reject the claim that 40% of home buyers find their real estate agents through a friend?
