When you take samples of size n - 100 from a normally distributed population, what will likely be the shape of the distribution of sample means? Right Skewed Left Skewed Normal

Which statement accurately describes the proportions in the tails of a normal distribution? The proportion in the left-hand tail is smaller than the proportion in the right-hand tail. O Proportions in both the left-hand and right-hand tails tend to be relatively large. OProportions in both tails are the same., O Proportions in both tails are negative.

When determining sample size what do you do if the sample proportion is unknown? What are the requirements for using a normal distribution as an approximation to a binomial distribution?

what happens to the sample mean when sample size decrease? decrease stay the same increase cannot be predictable

A population of values has a normal distribution with 45.2 and a 67.7. You intend to draw a random sample of size n = 108. Please answer the following questions, and show your answers to 1 decimal place. Find the value separating the bottom 35% values from the top 65% values. Find the sample mean separating the bottpm 35% sample means from the top 65% sample means.
