Question

In September 1997, Philadelphia’s long-time commercial classical station, WFLN, was sold for $85,000,000 and changed formats. One week later, Temple University’s WRTI, an all-jazz station since 1958, acquired WFLN’s collection and added classical music to its format.
 
After the format change, WRTI aired classical music on weekdays from 6 a.m. until 6 p.m., and jazz from 6 p.m. until 6 a.m. Saturday daytime hours were devoted to classical music (except for a 30-minute talk show at 6 a.m. and a 40-minute arts news show at 11 a.m.), while Sunday daytime hours were devoted to gospel or jazz until 3 p.m. Weekends also included syndicated programs such as  Piano Jazz ,  Jazz 20 Profiles , and  From the Top , as well as live broadcasts of performances by the Metropolitan Opera in season.
 
WRTI’s swift move not only prevented the demise of classical music radio in the nation’s sixth largest market but also benefited the station by drawing increased listeners and contributions, particularly from audiences left without another dedicated classical option after WFLN’s format change.In the summer of 1997, prior to adding classical music broadcasts, the station had approximately 6,500 average-quarter-hour (AQH) listeners. By the fall of 2005, the AQH audience had reached 18,300—a gain of 180%.
 
Membership also grew. In June 1997, WRTI had 3,371 members; one year later, membership was 9,411. It continued to rise, reaching 15,000 by 2005. In 1997, the station received approximately $259,000 in member contributions. In 1998, this amount increased to about $390,000. Member contributions continued to rise almost every year, surpassing $1,000,000 in 2003. In 2005, the station garnered $1,200,000 from members.
 
A decline in contributions and membership numbers in 1999 and 2001 reflected some strain from the station’s rapid growth. To manage the expansion, the station hired a chief financial officer in 1999 and a membership director in 2001. Both members and contributions rose following these staff additions.The graph below shows WRTI’s total number of members and total member contributions for each year from 1996 through 2005. The left vertical axis represents the number of members. The right vertical axis represents total contributions in dollars.

Official Solution:

After acquiring WFLN’s collection, WRTI allocated more total airtime per week to classical music than to jazz. 
 
• Tab 1 states that on weekdays, WRTI aired classical music from 6 a.m. to 6 p.m. and jazz from 6 p.m. to 6 a.m., resulting in an equal weekday split. On Saturdays, classical music aired during the daytime except for a 30-minute talk show and a 40-minute arts news program. On Sundays, gospel or jazz aired until 3 p.m., but it is unclear what was broadcast afterward. The weekend nighttime schedule and the durations of syndicated and seasonal programs are not specified. Because the full weekly distribution of airtime between classical music and jazz is not known, the statement cannot be confirmed.
 
 From 1997 through 2005, WRTI had a greater percent increase in its average-quarter-hour (AQH) listenership than in its number of members. 
 
• Tab 2 states that AQH listeners increased from approximately 6,500 in 1997 to 18,300 in 2005, a gain of 180%. Over the same period, membership increased from 3,371 to 15,000, a gain of more than 340%. Since 340% is substantially greater than 180%, the statement is incorrect. Not supported.
 
 The average contribution per member changed by less than 10% from 1997 to 2005. 
 
• In 1997, Tab 2 reports 3,371 members and approximately $259,000 in member contributions. This gives an average of about $77 per member. In 2005, with 15,000 members and $1,200,000 in contributions, the average was exactly $80 per member. The difference is $3, which is less than a 10% change. Therefore, this statement is supported.

Correct answer:

After acquiring WFLN’s collection, WRTI allocated more total airtime per week to classical music than to jazz.  "Not supported"

From 1997 through 2005, WRTI had a greater percent increase in its average-quarter-hour (AQH) listenership than in its number of members.  "Not supported"

The average contribution per member changed by less than 10% from 1997 to 2005  "Supported"

Hi  Bunuel

Could you please help me understand if the phrasing "from X to Y" means we are comparing the end points and not the year to year change? I thought that option c meant that every one-year jump was less than 10% and ended up selecting the wrong answer...

Thank you

Bunuel · Answer

“From X to Y” means comparing only the values in X and Y, not year-by-year changes.

MegB07 · Answer

I did not quite understand the solution. Hi, in the first option i marked as supported because based on the given information the time alloted to classical music was more than jazz.

The question does ask us to mark supported if the statement can be reasonably inferred from the paragraph.

How can we mark it as not supported?

Here is OE:

After acquiring WFLN’s collection, WRTI allocated more total airtime per week to classical music than to jazz. 
 
• Tab 1 states that on weekdays, WRTI aired classical music from 6 a.m. to 6 p.m. and jazz from 6 p.m. to 6 a.m., resulting in an equal weekday split. On Saturdays, classical music aired during the daytime except for a 30-minute talk show and a 40-minute arts news program. On Sundays, gospel or jazz aired until 3 p.m., but it is unclear what was broadcast afterward. The weekend nighttime schedule and the durations of syndicated and seasonal programs are not specified. Because the full weekly distribution of airtime between classical music and jazz is not known, the statement cannot be confirmed.
 
________________________________________________________________

Weekdays are 12 hours classical and 12 hours jazz, but weekend nights, the hours after 3 p.m. on Sunday, and the exact lengths of syndicated and opera programs are not given. Since we do not have the full breakdown, we cannot confirm that classical received more airtime overall. That is why the correct marking is “Not supported.”

I like the solution - it’s helpful. For the third, since calculations was involved, would have been easier to have definite y-axis values.
Since it's in-between, I approximated a bit and ended up with wrong answer (>10% change)
