- I need help with the 2 questions. Thanksidentify the sample space of the probability experiment and determine the number of outcomes in the sample space. Randomly choosing a number from the even numbers between 10 and 20, inclusive. The sample space is _____. * use a comma to separate answers as needed. Use ascending order.Help please with section (a).it has 3 parts
- Throughout the semester we have seen the importance of standard deviation and how it is needed to calculate probabilities of certain outcomes. In chapter 11, you will find that a majority of the formulas are long. If you investigate the formulas, what you will find is that the formulas in chapter 11 are applications of the Pythagorean Theorem of Statistics. Let us use this concept to answer a seemingly impossible question. What is the probability that a randomly chosen woman will be taller than a randomly chosen man? And is that outcome usual or unusual? The mean height of men is 69 inches with a standard deviation of 3 inches. The mean height of women is 63.6 inches with a standard deviation of 2.5 inches. Let’s create a mean and standard deviation by combining the data set of men and women. This is technically impossible because how is it possible to collect an entire data set of men, let alone women. Let’s consider the set X – Y, where X represent the data set of women and Y…Please answer all sub-parts For a population with ? = 215 and ? = 30, what is the probability that a random sample of size 225 will have a sample mean (x bar) higher than 218?Please see below.
