To answer this question, we need to find the winning probability in either case.
Probability = no. of outcomes / total no. of possible outcomes
<u>When Hope pulled her defender :</u>
Total no. of games = 9
No. of games won = 3
Winning probability = 3/9 =1/3
<u>When Hope left her defender :</u>
Total no. of games = 10
No. of games won = 6
Winning probability = 6/10 = 3/5
We know that , 1/3 < 3/5.
So, Hope should not pull her defender, as the winning probability is better when Hope left her defender.
Answer : A. Hope should not pull her defender.
Answer: a) 683 b) 1067
Step-by-step explanation:
The confidence interval for population proportion is given by :-
a) Given : Significance level :
Critical value : 
Margin of error : 
Formula to calculate the sample size needed for interval estimate of population proportion :-
Hence, the required sample size would be 683 .
b) If no estimate of the sample proportion is available then the formula to calculate sample size will be :-
Hence, the required sample size would be 1067 .
Answer:
12.5% Step 1 to find volume of Pyramid A Step 2 is find percentage through division then multiplication of 100
Step-by-step explanation: Length of one side of the base (a) = 14 in
Height of square pyramid (h) = 6 in
Using the square pyramid volume formula,
Volume = 1/3 x a^2 x h
Volume = 1/3 x 14^2 x 6
Volume = 392 in3
The volume Pyramid A is 392 cubic inches.
Pyramid A has a volume = 392 cubic units Pyramid B has a volume of 3,136 cubic inches. to find percentage 392 of 3136 we divide then * 100 To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator... = (392/3136 ) x 100% = 12.5% Proof is (12.5 * 3136 ) / 100 = 392
