A soda filling equipment, adjusted perfectly and in good condition, fills the bottles with 12 ounces of liquid. A random sample of 36 bottles is selected, and the contents are measured. The sample yielded an average content of 11.75 ounces, with a standard deviation of 0.52 ounces. With a 0.05 level of significance, test to see if the equipment is perfectly adjusted. Assume the distribution of the population is normal. *Show the 5 steps of hypothesis testing. Use both the critical and p-value approach – provide justification for your conclusion
