The answer is Mark. It was penned about that time and it was the first gospel written.
Staff is well trained
Physical environment is set to standards
There are C(29, 4) = 29!/(4! (29 - 4)!) ways of selecting any 4 students from the total 21 + 8 = 29 students.
The teacher has C(21, 2) = 21!/(2! (21 - 2)!) ways of picking out 2 sophomores and C(8, 2) = 8!/(2! (8 - 2)!) ways of picking out 2 freshmen, so there are
C(21, 2) • C(8, 2) = 5880
possible ways of picking out 2 sophomore and 2 freshmen.
The probability of picking out a group of students like this is then
C(21, 2) • C(8, 2) / C(29, 4) = 280/1131 ≈ 0.2476
The sampling distribution of the sample means for the random sample of 100 dogs will be 0.25.
<h3>How to compute the sample mean?</h3>
From the given information, the population distribution of the QDA scores for the fur of dogs is roughly uniform with mean 5.4 and standard deviation is 2.5.
In this case, the sampling distribution of the sample means will be:
= ✓SD/n
= ✓(2.5)²/100
= ✓0.0625
= 0.25
In conclusion, the correct option is 0.25.
