Astudy was done to determine the stress levels that students have while taking exams. the stress level was found to be normally distributed with a mean stress level of 8.2 and a standard deviation of 1.34. what is the probability that at your next exam, you will have a stress level between 9 and 10?

0.1841

Step-by-step explanation:

Given: Mean :

Standard deviation :

The formula to calculate z-score is given by :_

For x= 9, we have

For x= 10, we have

The P-value =

Hence, the probability that at your next exam, you will have a stress level between 9 and 10 = 0.1841

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
