Answer:
Yes, because the population distribution is normally distributed, and we have a random sample.
Step-by-step explanation:
If the population is skewed, then the sample mean won't be normal for when N is small.
If the population is normal, then the distribution of sample mean looks normal even if N = 2.
If the population is skewed, then the distribution of sample mean looks more and more normal when N gets larger.
Since we have use 33% of the student, then N is large enough to conclude that the student are bad at guessing
He should have found the GCF of 7 and 9, not 3 and 9.
Hello :),
3(-2x-1)=2(x+5)
-6x-3=2x+10
-6x-2x=10+3
-8x=13
x=13/-8=-1,625

Or 33 cm divided by 3 min=11 min
