Show answers and explanations

Practice questions

1. What is the model population?

Answer: 같은 회원 40명

The same 40 people are recorded twice.

  • 온라인 예약자만 40명 — The 40 include all three methods.
  • 두 시점의 사람을 합친 80명 — Do not add the same people twice.

2. How many more people used online booking?

Answer: 8명

20 minus 12 is 8 people.

  • 20명 — 20 is the later total.
  • 20%포인트 — That is a proportion gap, not a head count.

3. What is the gap from 30% to 50%?

Answer: 20%포인트

This is subtraction of percentages.

  • 20명 — Do not label proportions as people.
  • 모든 회원 — 50% is half, not everyone.

4. What cannot be established from this record?

Answer: 온라인 예약 증가의 원인

The record did not investigate causes.

  • 전체 회원 수 — The 40-person population is stated.
  • 온라인 예약 인원 — Counts appear in the table.

Learning check

1. What is the new chart’s population?

Answer: 같은 회원 50명

The three methods sum to 50 at each time.

  • 온라인 예약자 50명 — Online users are 10 or 20.
  • 서로 다른 100명 — These are repeated records of the same people.

2. How does online booking change in the task chart?

Answer: 10명에서 20명으로 늘었다.

April is 10 and October is 20.

  • 20명에서 10명으로 줄었다. — The time points are reversed.
  • 전체 50명이 온라인을 쓴다. — 20 is not the entire 50.

3. What is the change in online share?

Answer: 20%포인트

40% minus 20% is 20 percentage points.

  • 20명 — 20 people is the later count, not the share gap.
  • 10%포인트 — 10 is the increase in people.

4. How does in-person booking change?

Answer: 30명에서 25명으로 감소했다.

It decreased, but 25 people still use it.

  • 25명에서 30명으로 증가했다. — The time points are reversed.
  • 방문 예약이 없어졌다. — The count is 25, not zero.

5. Which method is most common in October?

Answer: 방문 예약 25명

25 exceeds 20 and 5.

  • 온라인 예약 20명 — Online increased but is not the largest.
  • 전화 예약 5명 — 5 is the smallest of the three.

6. Which summary is accurate?

Answer: 온라인은 늘고 방문·전화는 줄었지만 원인은 알 수 없다.

It describes the change and the record’s limit.

  • 방문 예약은 법으로 금지됐다. — No ban is described.
  • 온라인이 늘었으므로 모두 더 만족한다. — Satisfaction was not measured.
