or just approximate the numbers as 6 and 12 and the answer is 50.

Sajjad1994 · Answer

Official Explanation

The answer to the first question is C. About 12 calls an hour are received on Mondays and about 6 calls an hour on Wednesdays, so about 50% as many calls are received on Wednesdays as on Mondays.

The answer to the second question is A. On average, there is a decrease in the number of calls received over the course of the week, so the relationship between number of calls received and time since the beginning of the week is best described as not meaningful.

The fewest calls are received on Wednesdays, so that would be the best day for the clinic to assign fewer staff members to answering the phone. Answer to the III question is C.

Answer: C, A, and C

Hello Everyone!

C, A, and C.

$!vakumar.m · Answer

Hi  Sajjad1994 
I had a query on Question 2. The OE says, " On average, there is a decrease in the number of calls received over the course of the week , so the relationship between number of calls received and time since the beginning of the week is  best described as not meaningful. "
If there is a decrease in the number of calls received over the week, isn't the relationship negative. Why are we saying that it is not meaningful?

In most of the scatter point charts given in the Integrated Reasoning question, the average trend is taken and accordingly the relationship is defined.
Is it different in case of a bar chart, do we have to consider individual data points instead of taking an average.
Can you please help me in identifying what I am missing.
Thanks in advance.
Regards

Sajjad1994 · Answer

For the time being, forget the OE.

On Monday: approx 12 calls
Tuesday: approx 8 calls
Wednesday: approx 6 calls
Thursday: approx 8 calls
Friday: approx 7 calls

From Monday to Wednesday the number of calls decreases as the days progresses hence the relationship for the first three days is negative but then the number of calls start increasing and then again decreasing, making the relationship undefined. Hence overall the relationship is un-directional or not meaningful. OEs are not helpful sometimes.

mmdfl · Answer

I had the same doubt. "not meaningful" is very subjective, and this question becomes "harder" just because it is not well written. I put the data on chatGPT and it gave me a negative trendline (see attachment). "not meaninful" should be only for when the signal of the slope is impossible to be determined by eye, which is not the case here.

Sajjad1994 · Answer

The second question is ambiguous and hence archived.
