Answer:
Step-by-step explanation:
When A, B,C are equally likely to be assigned to any one of the stations 1,2 or 3
we find that each one assigned to one station has probability 1/3
Also each person is independent of the other.
Probability that
a) All three family members are assigned to the same station
= P(ABC) to same station
= P(ABC) to 1+P(ABC) to 2 +P(ABC) to 3
=3*P(A)P(B)P(C) since independent
=
b) This would be equivalent to 1- all 3 to the same station
= 
c) Every member to a different station
A has 3 choices while B has remaining 2 and C has 1
Hence prob = 
Answer:
10 or x=10
Step-by-step explanation:
First we can combine like-terms.
8x+6=86
Then subtract 6 from both sides
8x=80
Divide by 8
x=10
Answer:
A.
Step-by-step explanation:
Yes, because the critical value method uses critical value(s) to identify the rejection region(s). The P-value method compares the P-value with the level of significance alpha.
Explanation: When you reduce your significance value, the critical value either gets smaller, or larger depending on the tails. This means that your test statistic would also have to get smaller or larger depending on the tail in order to reject the null hypothesis.
At test that rejected the null hypothesis at 5% may not reject it at 1%
Answer:
5.75
You divide 19.55 by 3.4
Which gives you exactly 5.75
Ends up being ten after all the steps but if you add one after that the answer is 11
