Householders are polled on whether they support a tax increase to build more schools. The householders are also asked whether their annual household income is above or below $60,000. The results of the poll found 106 householders with an annual income above $60,000 of whom 32 support the tax increase and 221 householders with an annual income below $60,000 of whom 106 support the tax increase. Provide a two-sided analysis to investigate the evidence that the support for the tax increase depends upon the householder's income.
