The Thneedville governing cabal wants to distribute stimulus packets to needy Thneed households. A Thneed household is needy if they own fewer than 31 marbles. The most recent NTS (Needy Thneed Service) data indicates that 41% of all Thneed households are needy. On the other hand, that data is more than 2 years old, and Frederick Thneed Jr. suspects that the current percentage of needy Thneed households is lower than 41%, and they decide to perform a significance test to justify their belief. The hypotheses for this test are H0: Population % = 41%; HA: Population % #41%. Frederick surveys a simple random sample of n=100 households, and finds that 35 of them are needy.
