Chapter Review
7.1 the central limit theorem for sample means (averages).
In a population whose distribution may be known or unknown, if the size ( n ) of the sample is sufficiently large, the distribution of the sample means will be approximately normal. The mean of the sample means will equal the population mean. The standard deviation of the distribution of the sample means, called the standard error of the mean, is equal to the population standard deviation divided by the square root of the sample size ( n ).
7.2 The Central Limit Theorem for Sums (Optional)
The central limit theorem tells us that for a population with any distribution, the distribution of the sums for the sample means approaches a normal distribution as the sample size increases. In other words, if the sample size is large enough, the distribution of the sums can be approximated by a normal distribution, even if the original population is not normally distributed. Additionally, if the original population has a mean of μ X and a standard deviation of σ x , the mean of the sums is nμ x and the standard deviation is ( n ) ( n ) ( σ x ), where n is the sample size.
7.3 Using the Central Limit Theorem
The central limit theorem can be used to illustrate the law of large numbers. The law of large numbers states that the larger the sample size you take from a population, the closer the sample mean, x ¯ x ¯ , gets to μ .

What is a Sampling Distribution? Day 2
Chapter 7 - day 2 - lesson 7.1, all chapters, learning targets.
Use the sampling distribution of a statistic to evaluate a claim about a parameter.
Determine if a statistic is an unbiased estimator of a population parameter.
Describe the relationship between sample size and the variability of a statistic.
Activity: What was the average for the Chapter 6 test?
Answer Key:
Just like the lesson from yesterday , students will be trying to estimate the mean Chapter 6 test score using a sample mean (statistic). Today we are looking at the much more realistic population of all AP Stats students (85 this year at East Kentwood High School!) You will need to have your Chapter 6 Test scores (no names!) available to give to students for this Activity.
"What does this dot represent?"
In the Activity, students create a dotplot on a posterboard at the front of the room. Once completed, point at one of the dots and ask students “What does this dot represent?”. The ideal response is “a sample of 5 test scores and an average calculated from that sample”. Then point to another dot and ask again “What does this dot represent?”. Students should respond with “A different sample of 5 test scores and an average calculated from that sample”. In the end, they recognize that a sampling distribution represents many, many samples of 5 test scores and an average calculated for each.
Bring it back to Beyonce
Remind students on this Activity from Chapter 4. We were trying to estimate the average word length from Crazy in Love by Beyonce, so that we could evaluate the claim that she did not write the lyrics. The first sampling method had students quickly circle five words and find the mean. It is likely that most of your students overestimated the true mean word length. Put another way, the mean of the sampling distribution was much greater than the true mean of the population. This is exactly the definition of a biased statistic.
We then tried a second approach (using an SRS) which did produce an unbiased statistic (hopefully just like your students estimates of the Chapter 6 test average from the activity today).

Χ = amount of change students carry; Χ ~ Exp(1/0.88) or approximately Χ ~ Exp(1.1364); X ¯ X ¯ = average amount of change carried by a sample of 25 students.; X ¯ X ¯ ~ N(0.88, 0.176); 0.0819; 0.4276; The probability in part (e) represents the probability of an individual value. In part (f), the probability describes the mean of a sample of 25.

a statistic used to estimate a parameter in an unbiased estimator if the mean of its sampling distribution is equal to the value of the parameter being estimated. variability of a statistic. described by the spread of its sampling distribution. This spread is determined mainly by the size of the random sample. Larger samples give smaller spreads.
