Answer:
60 time 10
Step-by-step explanation:
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:
Groceries Galore
Step-by-step explanation:
1) Find the value of 1 egg for each shop.
<u>Max's Market: </u>
2.04 ÷ 6

2.64 ÷ 8
= £0.33
<u>Fancy Foodstuffs:</u>
4.08 ÷ 12
= £0.34
Therefore, Groceries Galore's price per egg is cheaper.
