Answer:
Step-by-step explanation:
We are given a joint probability table.
There are four different graders in a school
1. Grade Ninth
2. Grade Tenth
3. Grade Eleventh
4. Grade Twelfth
Field trip refers to the students who will attending the amusement park field trip.
No field trip refers to the students who will not be attending the amusement park field trip.
We want to find out the probability that the selected student is an eleventh grader given that the student is going on a field trip.
Where P(eleventh and FT) is the probability of students who are in eleventh grade and will be going to field trip
Where P(FT) is the probability of students who will be going to field trip
So the required probability is
Answer:
Assuming population data
Assuming sample data
Step-by-step explanation:
For this case we have the following data given:
736.352, 736.363, 736.375, 736.324, 736.358, and 736.383.
The first step in order to calculate the standard deviation is calculate the mean.
Assuming population data
The value for the mean would be:
And the population variance would be given by:
And we got
And the deviation would be just the square root of the variance:
Assuming sample data
The value for the mean would be:
And the population variance would be given by:
And we got
And the deviation would be just the square root of the variance:
