- if both parents are carriers (heterozygous) for a gene responsible for a genetically inherited disorder the probability of baby having 0.25 to have 6 kids, calculate the probability that at least 2 lids will have the disorder. the correct answer is between 0.41 and 0.49 and we are supposed to use the binomial distribution equation, but I am having trouble plugging the numbers in correctly can someone help?Mathew determines that the “power” for detecting a posttest score of the size Mathew expects with his experiment is .9999. Explain what the power means in words. .9999 is the probability that Mathew concludes the mean posttest score is greater than 7 when the actual mean gain score is greater than 7. .9999 is the probability that Mathew fails to conclude the mean posttest score is greater than 7 when the actual mean gain score is greater than 7. .9999 is the probability that Mathew concludes the mean posttest score is greater than 7 when the actual mean gain score is not greater than 7. .9999 is the probability that Mathew fails to conclude the mean posttest score is greater than 7 when the actual mean gain score is not greater than 7.A random sample of size 100 is taken from a normalpopulation with σ = 25.

What is the probability that the mean of the sample would be greater than 186.6186.6 points if 7373 exams are sampled? Round your answer to four decimal places.
- Suppose, you are running an experiment that has two outcomes, namely 'success' and 'failure'. You intially don't know the probability of success in a single experiment. But you know that, if you continue to run the experiment several times, the expected number of experiment required for the first success is 8. What is the standard deviation of the number of experiments required for the first success? In details.Suppose that a random sample of size 25 is to be selected from a population with mean 46 and standard deviation 8. What is the approximate probability that X will be more than .5 away from the population mean?Researchers developed a "cat IQ test" and find that the population of cats in the United States has a mean score of u = 25 on this test with a standard deviation of g = 3. You decide to test a sample of n = 45 cats to do some research about whether some breeds are smarter. You collect your sample of n = 45 cats and find their mean cat IQ is M = 25.5. What is the probability of this sample? That is, what is p(M>25.5)?
