Homework Answers
The Central Limit theorem states that the sampling distribution of sample mean approaches to normal as the sample size increases no matter what was the distribution of the population.
Based on this,
b) Collect a sample of people, treating the sample mean as one unit in the new distribution
is the correct answer

Applying the Central Limit Theorem: The amount of contaminants that are allowed in food products is determined by the FDA (Food and Drug Administration). Common contaminants in cow milk include feces, blood, hormones, and antibiotics. Suppose you work for the FDA and are told that the current amount of somatic cells (common name "pus") in 1 cc of cow milk is currently 750,000 (note: this is the actual allowed amount in the US!). You are also told the standard deviation...

Joseph ring 【Problem description】 N people numbered as 1,2...,n sit in a circle in clockwise, and each has only one password of positive integer. Firstly a positive integer is arbitrarily selected as the upper limit value m, then numbering off from 1 to m in clockwise is carried out, and the person reporting m will leave the circle and his password will be used as the new m value for the next round of numbering off. This process will carry...

3. Applying the central limit theorem Suppose you are a television network executive interested in how a new pilot show, Statistics, will be received by the general U.S. television-viewing population. You hire several market research firms; each recruits a random sample of television viewers and asks them to watch the pilot of Statistics. Each firm then gathers 25 respondents and asks each of them, "On a scale of 1 to 10, where 1 means you'll never watch Statistics again, and...

You will be performing an analysis on heights in the US population, broken out by gender. You will need to know that US heights for males and females both follow an approximately normal distribution. The average height for women is 63.7 inches and a standard deviation of 2.7 inches. The average height for men is 69.1 inches and a standard deviation of 2.9 inches. You will use these numbers in your calculations. Steps (all statistical analysis to be done in...

/courses/1631958/q 2791378/take D Question 5 12 pts Pulse Rates of Men. A simple random sample of 40 men results in a standard deviation of 10.3 beats per minute (based on the data set provided). The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with...
