analysis needs to address the following issues:
The battery temperatures are a major concern for us. Can you analyze and describe the sample data? What are the average and median temperatures? How much variability is there in the temperatures? Is there anything that stands out?
Our engineers’ assumption is that the temperature data is normally distributed. If that is the case, what would be the likelihood that the Safety Zone temperature will exceed 5.15 degrees? What is the probability that the Safety Zone temperature will be less than 4.65 degrees?
What is the actual percentage of samples that exceed 5.25 degrees or are less than 4.75 degrees?
Is the manufacturing process producing units with stable Safety Zone temperatures? Can you check if there are any apparent changes in the temperature pattern? Are there any outliers? A closer look at the Z-scores should help you in this regard.

- agree or disagree with this post Face - “Face” or dignity in a negotiation has been called “one of an individual’s most sacred possessions.”102 Face is the value a person places on his or her public image, reputation, and status vis-à-vis other people in the negotiation. Direct threats to face in a negotiation include making ultimatums, criticisms, challenges, and insults (Thompson, 2019). A good example of face is when I go to the negotiation table with a counterpart that is known to be difficult or not as knowledgeable about the category as they should be, my approach wouldn't be to point out their weakness, I will respect their thought process, show consideration for their perspective, all while guiding the conversation in the direction of my intended negotiation strategy in hopes to achieve my desired outcome.
