Question
Please help A coin is biased. Danny wished to determine the probability of obtaining heads when flipping this coin. He flips the coin 10 times and obtains 8 heads. He concludes that the probability of obtaining heads when flipping this coin is 0.8. Is his thinking reasonable? Why or why not? Find the indicated probability or for the sampling error. Scores on an aptitude test are normally distributed with a mean of 220 and a standard deviation of 10. Determine the percentage of samples of size 25 that have a mean score within 3 points of the population mean score of 220. Find the confidence interval specified. Physiologists use the forced vital capacity as a way to assess a person's ability to move air in and out of their lungs. A researcher wishes to estimate the forced vital capacity of people suffering from asthma. A random sample of 15 asthmatics yields the following data on forced vital capacity, in liters. 4.6 3.0 4.1 4.1 5.2 4.1 3.7 4.3 3.5 5.2 3.2 35 4.8 4.0 5.1 Use the data to obtain a 95.44% confidence interval for the mean forced vital capacity for all asthmatics, Assume that sigma = 0.7.Explanation / Answer
3)coin is baised
that means
Outcomes are not equally likely, they might be equal or might not be equal, it Is biased coin.
probability of getting head not equal to probability of getting tail for tossing a baised coin.
in this probem,
coin is favourable in getting head instead of getting tail by tossing coin 10 times we get 8 heads
it means ,he thinking reasonable for the purpose
