5. Roll the die another 40 times and calculate the value of x. Sample Mean Observation (= second observation of X): 6. Now write your two X values (one from question 2 and one from question 5). Comment on the values. 7. The random variable X represents the outcome of a single roll of the die, and the random variable X represents the sample mean of 40 rolls of the die. Use the Central Limit Theorem, and the values in...

1. Explain the relationship between sample size and standard error. 2. You have a normal population with a u = 50 and o = 9. You obtain all possible random samples, each with n = 30, from this population and calculate each sample's mean. What will the average value of all the sample means be? a) 50 b) 5.56 c) 30.49 d) Cannot tell without more information 3. You are sampling from a distribution of scores that is positively skewed....

As you are answering each question, please explain your answers in addition to picking what you believe to be the correct letter choice. 1. You conduct a hypothesis test with a sample of size n = 40 and you observe values for the sample mean and sample standard deviation that do not lead to the rejection of the null hypothesis. In fact, you determine the p-value is 0.0667. What would you expect to happen to the p-value if the sample...

Chapter 18, Problem 09 Two spherical objects are separated by a distance of 1.55 x 103 m. The objects are initially electrically neutral and are very small compared to the distance between them. Each object acquires the same negative charge due to the addition of electrons. As a result, each object experiences an electrostatic force that has a magnitude of 4.69 10-21 N. How many electrons did it take to produce the charge on one of the objects? Number Units...
