WebOct 17, 2015 · 1 Answer. Chandra S. Oct 17, 2015. Not always. The parameter 'p' in Binomial Distribution decides whether the distribution is symmetric or not. If p = 1/2, … WebFeb 6, 2024 · 71 1 6. If p=1/2 the binomial is symmetric and hence the mean is equal to the median. Since P (X<15)<1/2 the median and hence the mean also are greater than 15. Now the mean for the binomial is np=n/2 in this case.Now n/2 is greater than 15. so n>30. Choice 2 is the answer.
WebJan 10, 2024 · A distribution is asymmetric if it is not symmetric with zero skewness; in other words, it does not skew. An asymmetric distribution is either left-skewed or right-skewed.

WebGiven n and p, it is simple to compute the probability of a particular number of successes directly using the binomial distribution. One can then examine the distribution to see … WebThe mean and variance of a negative binomial distribution are n 1 − p p and n 1 − p p 2. The maximum likelihood estimate of p from a sample from the negative binomial …
WebA probability distribution is said to be symmetric if and only if there exists a value such that for all real numbers where f is the probability density function if the distribution is continuous or the probability mass function if the distribution is discrete . Multivariate distributions [ edit]
WebWe have noted previously that the Binomial tends to the Normal Distribution when n is large and p is not small, with the approximation being best when p is close to 0.5 because in this case the Binomial is symmetric for all n. in ways that 用法WebShape. Binomial distributions can be symmetrical or skewed. Whenever p = 0.5, the binomial distribution will be symmetrical, regardless of how large or small the value of n. However, when p ≠ 0.5, the distribution will be skewed. If p < 0.5, the distribution will be positive or right skewed. only personality testsWebThe distribution will always be symmetric. O C. The distribution will be symmetric only if n is large. OD. The distribution will be right-skewed. -icb etric sym bution This problem has been solved!
