A coin was flipped 60 times and came up heads 38 times At the 10 level of significance is the coin biased toward heads?

Possibly not - the sample of 60 times is very small.

A coin is biased so that the probability a head comes up when it is flipped is 0.6 What is the expected number of heads that comes up when its flipped 10 times?
Multiply the probability by the number of times the experiment was carried out. 0.6x10=6
In statistics which is better large sample size or small sample size?
Generally, the larger the sample the more reliable the results. Example: If you flipped a coin twice and got heads both times you could say the coined is biased towards heads. However, if you repeat the experiment 100 times your results will be a lot more reliable.
A coin is flipped eight times What is the probability that the outcome will NOT be eight heads?
Probability of not 8 heads = 1- Prob of 8 heads. Prob of 8 heads = 0.5^8 = 0.003906 Prob of not 8 heads= 1- 0.003906 = 0.99604
What is the probability that a coin flipped four consecutive times will always land on heads?
The probability that a coin flipped four consecutive times will always land on heads is 1 in 16. Since the events are sequentially unrelated, take the probability of heads in 1 try, 0.5, and raise that to the power of 4... 1 in 24 = 1 in 16
If I were to flip a coin 4 times. What is the probability of me getting heads twice?
If the coin is not biased, the answer is 0.375
A coin is flipped 60 times it lands on heads 36 times Do you think that the coin is biased?
yes the coin is biased because it turned to heads 36 times.
A coin is biased so that the probability a head comes up when it is flipped is 0.6 What is the expected number of heads that comes up when its flipped 10 times?
Multiply the probability by the number of times the experiment was carried out. 0.6x10=6
What are the possible outcomes of a coin that is flipped?
The possible outcomes of a coin that is flipped are heads or tails.
If you flipped a coin what would it be?
Heads or Tails
What is the chance that that 2 flipped coins both come up heads?
The probability that 2 flipped coins both come up heads is 0.52 or 0.25
What is theromental?
suppose you flipped a coin 100 times you might have flipped heads 50 time and tails 50 times
If you flipped two coins what is the probability that the first coin is heads?
The probability is always 50/50 even if you flipped 100 or 1000000 coins.
In statistics which is better large sample size or small sample size?
Generally, the larger the sample the more reliable the results. Example: If you flipped a coin twice and got heads both times you could say the coined is biased towards heads. However, if you repeat the experiment 100 times your results will be a lot more reliable.
What is the probability of heads commming up when a coin is flipped?
Fifty percent (50%)
What is the probability of flipping 3 heads?
The answer depends on how many coins are flipped, and how often.
What is the probability of a coin landing on heads twice when it is flipped 2 times?
25%
What is the number of possible results that a flipped penny lands on heads?
1/2
