In a survey of 150 randomly selected coal miners in State A, 7 support government subsidies to encourage producing solar energy. In a survey of 150 randomly selected farmers in State B, 132 support such subsidies. Compute the test statistic for a hypothesis test to compare the population proportion of coal miners in State A that support such subsidies to the proportion of farmers in State B that support such subsidies. Assume that the conditions for a hypothesis test for the difference between the population proportions are met. Round your answer to two decimal places.
