A cоmpаny hаs develоped а new deluxe AAA battery that is suppоsed to last longer than its regular AAA battery. However, these new batteries are more expensive to produce, so the company would like to be convinced that they really do last longer. Based on years of experience, the company knows that its regular AAA batteries last for 30 hours of use, on average. The company selects an SRS of 50 new deluxe batteries and uses them continuously until they are completely drained. The sample mean lifetime is x¯=33.9{"version":"1.1","math":"x¯=33.9"}. A significance test is performed. If H0:μ=30{"version":"1.1","math":"H0:μ=30"}, then what is the alternative hypothesis?
