What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) Ho: P = V HA: P * v Based on the hypotheses, find the following: Test Statistic = p-value = Based on the above we choose to Fail to reject the null hypothesis The correct summary would be: There is not enough evidence to support the claim v V that the proportion of homes in Oregon that were heated by natural gas is different than what the DOE reported value of 48%
