Aaron and Sophie disagree about what fraction of this population has average family income below about $50 000. Aaron thinks about 50% of this population has average family income below about $50 000. Sophie thinks Aaron's fraction is just wrong. They agree to hypothesis test Aaron's estimate at level of significance 0.01, using the following annual income estimates from a random sample of fifteen such families: 18500,78500,41000,48500,33500,46000, 14000,56000,28500,31000,21000,36000,46000, 16000,36000 The sample proportion is The value of the test statistic is The critical numbers are and The P-value is
