*** Answer the question with the 5 steps please clearly written: 1) State null and alternate hypothesis, 2) Choose level of significance, 3) Find critical value (based on p-value or test-value), 4) Find test statistic, 5) Draw your conclusion.***

A machine dispenses 500 mL of fluid into a bottle. A customer believes the machine does not dispense 500 mL of fluid. Using 50 samples, the person measures that the average fluid dispensed is 480 mL with a standard deviation of 25 mL. At 5% level of significance, does this person have enough evidence to support the hypothesis???
