A sampling distribution shows every possible result a statistic can take in every possible sample from a population and how often each result happens - and can help us use samples to make predictions about the chance tht something will occur. This unit covers how sample proportions and sample means behave in ...The Central Limit Theorem states that if a sample size (n) is large enough, the sampling distribution of the sample mean will be approximately normal, regardless of the shape of the population distribution. In general, a sample size of n > 30 is considered to be large enough for the Central Limit Theorem to hold. 🔔.A random sample of 100 people will be selected from the population.

First, we subtract the mean score from the student's score to find the difference: 90 - 75 = 15. Next, we divide the difference by the standard deviation of the scores: 15 / 10 = 1.5. B. The z-score for the student's score is 1.5, which means that the student scored 1.5 standard deviations above the mean test score.

The response provides the correct test statistic and p-value. Although work was not required, the supporting work for the test statistic is correct; therefore, the response satisfies both components 1 and 2 of section 2. Because the response includes both of the components, section 2 was scored as essentially correct. The ©probability model is a description of some chance process that consists of two parts: a sample space S and. a probability for each outcome. For example: When a fair 6-sided die is rolled, the Sample Space is S = {1, 2, 3, ,4,5, 6}. The probability for a fair die would include the probabilities of these outcomes, which are all the same.
