Question 1208104: Assume that the reading on thermometer are normally distributed with a mean of 0 degree and standard deviation of 1 degree . A thermometer is randomly selected and tested. find the probability of each reading in degree, draw a sketch
a. Between 0 and 3
b. Between 0 and -2.33
c. Between 1.34 and 2.67
d. Less than 0.08
e. Between -1.99 and 2.01
f. Greater than 0.25
g. Less than -1.47
h. Find P90, the 90th percentile. This is the temperature reading separating the bottom 90% from the top 10%
i. Find Q1, the temperature reading that is the first quartiles
j. If 2.5% of the thermometers are rejected because they have reading that are too high and another 2.5% are rejected because they have readings that are too low. Find the two readings that are cutoff values separating the rejected thermometers from the others
Could you provide these solving and explain.
Answer by ikleyn(52756)   (Show Source):
You can put this solution on YOUR website! .
Please do not post 10 different problems in one post.
It is FAR BEYOND of the frames of a reasonable/rational behavior.
The rules of this forum allow to post one problem/question per post.
OK, we can admit three closely related problems/questions, but 10 is just toooooooooo much.
About these rules, read on this web-page
https://www.algebra.com/tutors/students/ask.mpl?action=ask_question&topic=Equations&return_url=http://www.algebra.com/algebra/homework/equations/
from which you post your problems.
It is assumed that you read these rules before posting.
It is also assumed that you do understand what is written in that page and follow the rules.
Those who violate them, work against their own interests.
Have a nice day ( ! )
