Q13:

A coin is flipped 100 times, and 59 heads are observed. Find a 80% confidence interval of π (the true population proportion of getting heads) and draw a conclusion based on the collected data. Hint: Choose the best one.

please answer in the same format as these examples below

A) (0.471, 0.596) a 80% confidence interval of π and we conclude it is a fair coin.

or

H) (0.633, 0.692) a 80% confidence interval of π and we conclude it is not a fair coin.

A coin is tossed 54 times and 39 heads are observed. Would we infer that this is a fair coin? Use a 97% level confidence interval to base your inference. The sample statistic for the proportion of heads is:  (3 decimals) The standard error in this estimate is:  (3 decimals) The correct z* value for a 97% level confidence interval is:  (3 decimals) The lower limit of the confidence interval is:  (3 decimals) The upper limit of the confidence interval is:  (3 decimals) Based on...

1 A fair coin is flipped 15 times. Each flip is independent. What is the probability of getting more than ten heads? Let X = the number of heads in 15 flips of the fair coin. X takes on the values 0, 1, 2, 3, ..., 15. Since the coin is fair, p = 0.5 and q = 0.5. The number of trials is n = 15. State the probability question mathematically. 2 Approximately 70% of statistics students do their...
