How could you say they are correct when he hasn't even put any answers?! Nonsense! You can only hold one status at a time is false. The average person never breaks a norm is true. Hope this helps!
If a juice drink filling machine, when in perfect adjustment, fills the bottles with 12 ounces of drink on an average and any overfilling or underfilling results in the shutdown and readjustment of the machine, in order determine whether or not the machine is properly adjusted, the correct set of hypotheses is H0: µ=12 and Ha: µ≠12. (Option C).
In scientific context, a hypothesis or hypotheses refers is a testable statement defining the relationship between variables or a proposed justification for an observed phenomenon. In this case, since the drink filling machine that is perfectly adjusted fills 12 ounces of drink on an average, after readjustment to determine if the machine is properly adjusted, the hypotheses that must be test that if the average of filling is equal to 12 ounces or not.
Note: The question is incomplete as options are missing. The options are a) H0: µ < 12 and Ha: µ≥12, b) H0: µ≤12 and Ha: µ>12, c) H0: µ=12 and Ha: µ≠12, d) H0: µ≠12 and Ha: µ =12.

All answers are correct except C. Since the US is a market economy, they are not set by the government. They act as signals to buyers and sellers by showing the sellers how much they should price their own products and show buyers how much value the product is. It also an indicator of the quality of a product because if it is more expensive, then the cost to make is able to make it more high quality (this is not always the case but generally). And lastly, it lets you know how much an item costs (no brainer). For me, the best answer would probably be A. act as signals to buyers and sellers
