Answer:
(1) The correct option is (A).
(2) The probability that Aadi will get Tails is .
Step-by-step explanation:
It is provided that:
- Eric throws a biased coin 10 times. He gets 3 tails.
- Sue throw the same coin 50 times. She gets 20 tails.
The probability of tail in both cases is:
(1)
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
In this case we need to compute the proportion of tails.
Then according to the Central limit theorem, Sue's estimate is best because she throws it <em>n = </em>50 > 30 times.
Thus, the correct option is (A).
(2)
As explained in the first part that Sue's estimate is best for getting a tail, the probability that Aadi will get Tails when he tosses the coin once is:
Thus, the probability that Aadi will get Tails is .
Answer:
Step-by-step explanation:
The running time for an input size of 1000 will be 25 seconds.
To calculate the runtime of the Algorithm we need to know what an Algorithm is and how its runtime works.
<h3>What is the runtime of an Algorithm?</h3>A finite sequence of rigorous instructions, used to solve a critical problem of a specific class or for computational purposes is called an Algorithm. The time taken to complete the said task is called the runtime of an Algorithm.
Let us now solve the question about linear running time of an algorithm.
Input size()=200
Time taken()=5 seconds
Final input size()=1000
Let the final time taken be T.
Now we know that:
Substituting the values we get seconds .
Therefore the linear running time for an input size of 1000 is 25 seconds.
