consider the problem of estimating the mean value of a population, and imagine a large number of hypothetical samples each with size n. the population variance is . the population distribution is right-skewed, heavy-tailed. for each sample, we can calculate the mean. so we will have a large number of mean values. we can plot their distribution. which is true about this distribution? group of answer choices it is normally distributed its distribution is the standard normal distribution its distribution is right-skewed, heavy-tailed, its mean is equal to the population mean, its standard deviation is given by its distribution is right-skewed, heavy-tailed, its mean is 0, its standard deviation is 1
