A restaurant owner installed a new automated drink machine. The machine is designed to dispense 530 mL of liquid on the medium size setting. The owner suspects that the machine may be dispensing too much in medium drinks. They decide to take a sample of 30 medium drinks to see if the average amount is significantly treated than 530 mL.

Jazz is a college basketball player who has made 75% of the free-throws she has attempted in her career. She decided to practice a new technique for shooting her free-throws. Jazz was curious if this new technique produced significantly better or worse results. She tried the new technique and made 70% of 50 attempts. Here is Jazz’s alternative hypothesis: Ha: The proportion of attempts made using this new technique is…
Not equal to 75%
