Answer:
we know that the average number of
the class is 30 so we divide 1/10*30
equals 3 pupils
The only correct answer is NE because it is the reverse to EN.
Answer:
54
Step-by-step explanation:
Add all of the numbers then divide by however many numbers there are in this case it would be 8. So it would be 432/8.
Answer:
A.0.39 grams
margin of error at 90% confidence intervals is
M.E = 0.39 grams
Step-by-step explanation:
<u>Explanation</u>:-
Given a sample of size n = 25
mean of the sample x⁻ = 15 grams
Standard deviation of the sample 'S' = 1.5 grams
<u>margin of error at 90% confidence intervals is determined by</u>
<u></u>
<u></u>
The degrees of freedom ν = n-1 = 25-1 =24
The tabulated value t₀.₉₀ = 1.318
Margin of error = 0.3954
<u>Conclusion</u>:-
Margin of error at 90% confidence intervals = 0.3954
Answer:
0.06
Step-by-step explanation:
The computation of the value of p is shown below;
P in the case (2 points if not fouled) = 0.6
Now Expected points if not fouled is
= 0.6 × 2
= 1.2
Now Expected points from free throw is
0 × (1-p)^2 + 1 × 2p(1-p) + 2 × p^2 = 2p
As we can see that 2p would be lower tha 1.2 in order to make a foul on shooter that represent all values of p<0.06 would be considered to foul in the shooter
