ARE THERE CHARGES IN VOLVED, According to a​ research,
According to a​ research, 52.052.0​% of households nationwide used natural gas for heating during a year.​ Recently, a survey of 2 comma 3002,300 randomly selected households showed that 53.053.0​% used natural gas. Use a 0.05 significance level to test the claim that the 52.052.0​% national rate has changed. Formulate the null and alternative hypotheses. Choose the correct answer below. A.
