C Spinning a coin, unlike tossing it, may not give heads and tails equal probabilities. I spun a penny 150 times and got 67 heads. We wish to find how significant is this evidence against equal probabilities, a. What is the sample proportion of heads? Round to 3 decimal places. b. Heads do not make up half of the sample. Is this sample evidence that the probabilities of heads and tails are different? Take p to be the probability of...

An experiment consists of tossing an unfair coin (49% chance of landing on heads) a specified number of times and recording the outcomes. (a) What is the probability that the first head will occur on the second trial? (Use 4 decimal places.) Does this probability change if we toss the coin three times? What if we toss the coin four times? The probability changes if we toss the coin four times, but does not change if we toss the coin...

A special novelty coin has a probability of 0.89 of coming up heads. In 12 tosses of this coin: a) What is the probability the coin comes up heads exactly 10 times? Round your response to at least 3 decimal places. b) What is the probability the coin comes up heads more than 10 times? Round your response to at least 3 decimal places.

A coin is weighted so that there is a 60.4% chance of it landing on heads when flipped. The coin is flipped 13 times. Find the probability that at least 8 of the flips resulted in "heads". Round your answer to 4 decimal places.
A biased coin is tossed n times. The probability of heads is p and the probability of tails is q and p=2q. Choose all correct statements. This is an example of a Bernoulli trial n-n-1-1-(k-1) p...
A biased coin is tossed n times. The probability of heads is p and the probability of tails is q and p=2q. Choose all correct statements. This is an example of a Bernoulli trial n-n-1-1-(k-1) p'q =np(p + q)n-1 = np f n- 150, then EX), the expected value of X, is 100 where X is the number of heads in n coin tosses. f the function X is defined to be the number of heads in n coin tosses,...

Fair Coin? In a series of 100 tosses of a token, the proportion of heads was found to be 0.58. However, the margin of error for the estimate on the proportion of heads in all tosses was too big. Suppose you want an estimate that is in error by no more than 0.05 at the 95% confidence level. (a) What is the minimum number of tosses required to obtain this type of accuracy? Use the prior sample proportion in your...

Use the following simulation to answer the questions. Assume you are flipping an unfair coin 20 times and calculating the proportion of times the 20 flips turn up heads. You repeat this 100 times and the simulation output is as follows. The probability of this unfair coin to come up heads is 0.40 Probability of success (TT): 0.4 Summary Stats Sample size (n): 20 Mean .0400 Number of samples: 100 SD...

If you throw exactly two heads in two tosses of a coin you win $75. If not, you pay me $21 step 1.Find the expected value of the proposition. Round your answer to two decimal places. Losses must be expressed as negative values step 2. If you played this game 700 times how much would you expect to win or lose? Round your answer to two decimal places. Losses must be entered as negative
