Solution Steps

Step 1: Gather the Data

We have the number of messages sent by each individual:

  • Sean: 120
  • Emma: 95
  • Stanley: 101
  • Stacey: 125
  • Kevin: 82
  • Michelle: 108
  • Katie: 90
Step 2: Calculate the Sum of Messages

To find the mean, we first calculate the total number of messages sent by all individuals: \[ \sum_{i=1}^{7} x_i = 120 + 95 + 101 + 125 + 82 + 108 + 90 = 721 \]

Step 3: Calculate the Mean

The mean number of messages sent is calculated by dividing the total number of messages by the number of individuals: \[ \mu = \frac{\sum_{i=1}^{7} x_i}{7} = \frac{721}{7} = 103.0 \]

Final Answer

The mean number of messages sent is \(\boxed{103.0}\).

Douglas just finished his first job interview. Armed with knowledge from his Business Soft Skills course, Douglas attempted to use his body language to his advantage. He sat up so straight his back hurt, made eye contact until his eyes felt dry, and focused all his leftover energies into controlling his facial expressions. When the interviewer mentioned something of concern, Douglas quickly smoothed out his eyebrow line to mask it. While Douglas seems to have chosen the right behaviors, what is the potential pitfall? Douglas's brief eyebrow raise may have signaled his displeasure and cost him the interview. The interviewer may have been watching for body language signals of which Douglas is unaware. Since it is difficult to control all body language signals in a genuine way, Douglas's efforts may have seemed forced and unnatural. Douglas's body language may have been viewed as an aggressive power play.
