if you ever swam in a pool and your eyes began to sting and turn red, you felt the effects of an incorrect ph level. ph measures the concentration of hydronium ions and can be modeled by the function p(t) = −log10t. the variable t represents the amount of hydronium ions; p(t) gives the resulting ph level.
water at 25 degrees celsius has a ph of 7. anything that has a ph less than 7 is called acidic, a ph above 7 is basic, or alkaline. seawater has a ph just more than 8, whereas lemonade has a ph of approximately 3.

Astudy was interested in determining if eating milk chocolate lowered someone's cholesterol levels. ten people's cholesterol was measured. then, each of these individuals were told to eat 100g of milk chocolate every day and to eat as they normally did. after two weeks, their cholesterol levels were measured again. is there evidence to support that their cholesterol levels went down? how should we write the alternative hypothesis? (mud = the population mean difference= before - after)a. ha: mud = 0b. ha: mud > 0c. ha: mud < 0d. ha: mud does not equal 0
