Multiple Choice

"No, the elementary school students did not sell more small bottles than the middle school students."

• E

• P

• I

Multiple Choice

"No. Let x=number of bottles sold

Elementary small = 0.5x ______ Middle small = (3)(1/3)x = x

1x > 0.5x so the middle school students sold more small bottles"

• E

• P

• I

Multiple Choice

"The middle school students sold more small bottles. They sold 3 times as many bottles overall, which means they sold twice as many small bottles because 1 is greater than 0.5"

• E

• P

• I

Multiple Choice

"The administrator is incorrect. For example, if the elementary students sold 100 bottles total, 50 would be small. That means the middle school students would sell 300 total and 1/3 of them or 100 would be small."

Multiple Choice

"(i) High School A. The frequency of bottles sold at HSA is greater than that of HSB.

(ii) High School B. The area for HSB is much larger than the area for HSA."

• E

• P

• I

Multiple Choice

"(i) High School A. HSA sold 0.7, which is greater than HSB, which sold 0.6.

(ii) High School B. The dark shaded area for HSB is greater than the dark shaded area for HSA."

• E

• P

• I

Multiple Choice

"(i) High School A. 0.7 > 0.6

(ii) High School B. HSB seems to have sold about 3 times as many bottles as HSA. So if HSA sold 100 bottles, (100)(0.7)=70 are large. Then HSB will have sold 300 bottles and (300)(0.6)=180 are large. So HSB sold more large bottles than HSA."

• E

• P

• I

Multiple Choice

"(i) High School A. The relative frequency for HSA large bottles sold > the relative frequency for HSB.

(ii) High School B. The width for HSB is much larger than that of HSA, almost 3 times wider, so HSB sold more large bottles than the HSA."
