You have just been diagnosed with otitis media. Describe what has happened to your body to produce this condition. If left untreated, what are the possible outcomes of this condition?

Let p be the population proportion for the situation. Find point estimates of p and q. In a survey of 2016 U.S. adults, 1310 think mainstream media is more interested in making money than in telling the truth.

If a triangle were cut out of a sheet of wood or paper, the triangle could be balanced around exactly one point inside the triangle.

A median of a triangle is a segment whose endpoints are a vertex of a triangle and the midpoint of the opposite side.

Every triangle has three distinct medians. You can use construction tools to show that the intersection of the three medians is the balance point of the triangle.

(A) Draw a large triangle on a sheet of construction paper. Label the vertices $A, B$, and $C$.

(B) Find the midpoint of the side opposite $A$, which is $\overline{B C}$. You may use a compass to find points equidistant to $B$ and $C$ and then draw the perpendicular bisector. Or you can use paper folding or a ruler. Write the label $X$ for the midpoint.

(C) Draw a segment to connect $A$ and $X$. The segment is one of the three medians of the triangle.

(D) Repeat Steps B and C, this time to draw the other two medians of the triangle. Write the label $Y$ for the midpoint of the side opposite point $B$, and the label $Z$ for the midpoint of the side opposite point $C$. Write the label $P$ for the intersection of the three medians.

(E) Use a ruler to measure the lengths of each median and the subsegments defined by $P$ in your triangle. Copy the table and record your measurements.

(F) What pattern do you observe in the measurements?

(G) Let $A X$ be the length of any median of a triangle from a vertex $A$, and let $P$ be the intersection of the three medians. Write an equation to describe the relationship between $A P$ and $P X$.

(H) Let $A X$ be the length of any median of a triangle from a vertex $A$, and let $P$ be the intersection of the three medians. Write an equation to show the relationship between $A X$ and $A P$.

(I) Cut out the triangle, and then punch a very small hole through $P$. Stick a pencil point through the hole, and then try to spin the triangle around the pencil point. How easily does it spin? Repeat this step with another point in the triangle, and compare the results.

By definition, median $\overline{A X}$ intersects $\triangle A B C$ at points $A$ and $X$. Could it intersect the triangle at a third point? Explain why or why not.

A study of the use of social media asked a sample of 488 American adults under the age of 40 and a sample of 421 American adults aged 40 or over about their use of social media. Based on their answers, each subject was assigned a social media usage score on a scale of O to 25. Higher scores indicate greater usage. The subjects were chosen by random digit dialing of telephone numbers. Are the conditions for two-sample t inference satisfied?

(a) Maybe: the SRS condition is OK but we need to look at the data to check Normality.

(b) No: scores in a range between O and 25 can't be Normal.

(c) Yes: the SRS condition is OK and large sample sizes make the Normality condition unnecessary.

Using a newspaper or other media sources, find and record the high and low temperatures in your area for five days. Calculate the average high and low temperatures for the five-day period.

The angle of incidence and angle of refraction along a particular interface between two media are $30^{\circ}$ and $40^{\circ},$ respectively. What is the critical angle for the same interface?

A median of a triangle is a segment joining a vertex to the midpoint of the opposite side. Show that the centroid of a triangle lies on each of its medians, at a distance two-thirds down from the vertex. Then use this fact to prove that the three medians intersect at a single point. Hint: Simplify the calculation by assuming that one vertex lies at the origin and another on the x-axis.
