Depression engulfs millions of Americans every day. A federal study reported that $10.9 \%$ of adults aged $18-24$ identified with some level of depression versus $6.8 \%$ of adults aged 65 or older (The Boston Globe, October 18, 2010). Suppose 1,000 young adults (18-24 years old) and 1,000 older adults (65 years old and older) responded to the study.

a. Develop the appropriate null and alternative hypotheses to test whether the proportion of young adults suffering from depression is greater than the proportion of older adults suffering from depression.

b. Calculate the value of the test statistic and the $p$-value.

c. At the 5% significance level, do the sample data suggest that young adults suffer more from depression than older adults?

How have changes in nutrition and health care changed the lives of older adults?

Acidic solutions have more _______ ions than ­­­­­_______­­­­ ions, while alkaline (basic) solutions are the reverse.

In humans, blood pH is maintained within a narrow range: acidosis occurs if the blood pH is below 7.35, and alkalosis occurs if the pH is above 7.45. Given that the pKw of blood is 13.63 at $37 ^ { \circ } \mathrm { C }$ body temperature), what is the normal range of [H3O+] and of [OH?] in blood?

a) Which ion has 30 protons and 28 electrons?

b) Which ion has 9 protons and 10 electrons?

In solid sodium chloride (table salt), chloride ions have one more electron than they have protons, and sodium ions have one more proton than they have electrons. These ions are separated by about $0.28 \mathrm{~nm}$. Calculate the electrostatic force between a sodium ion and a chloride ion.
