CLT for proportions. Define the term “sampling distribution” of the sample proportion, and describe how the shape, center, and spread of the sampling distribution change as the sample size increases when p = 0.1.
4. Suppose the population proportion is p = .6 and N=212000. What sample size is required for the sample proportion to be normally distributed? 5. If a population is slightly skewed and my sample size is 12, is the sample normally mean distributed? me a normal distribution for If n-83 what is the smallest population size N that will give 6. 4. Suppose the population proportion is p = .6 and N=212000. What sample size is required for the sample...
1. Access the Explore Coverage web app. Select "Confidence Interval for a Proportion", set p 0.5, n=50 and Confidence Level to 95. Select 10 samples. i) Click the Draw Samples button. Describe what appears: 1. What do the green/red squares represent? 2. What do the lines extending from the squares represent? ii) Click the Draw Samples button again until a red square (and lines) appears. What is the significance of a red square and lines? i) Continue generating samples until...
Please Help me to full the all blank (11 blanks in total) 6. The sampling distribution of the sample proportion In 2007, about 30% of new-car purchases in California were financed with a home equity loan. [Source: "Auto Industry Feels the Pain of Tight Credit," The New York Times, May 27, 2008.] The ongoing process of new-car purchases in California can be viewed as an infinite population Define p as the proportion of the population of new-car purchases in California...
19) The Sampling Distribution of the Sample Proportion is approximately Normal if np(1 – p) is > 10. If p = 0.1, how large must the Sample be in order for the Sampling Distribution of the Sample Proportion to be approximately Normal? (Round UP to the nearest whole number).
The standard deviation of a sample proportion p gets smaller as the sample size n increases. If the population proportion is p o.55, how large a sample is needed to reduce the standard deviation of p to σ, = 0.0047 (The 68-95-99.7 rule then says that about 95% of all samples will have p within 0.01 of the true p. Round your answer to up to the next whole number.)

Consider a sampling distribution with p=0.09 and samples of size n each. Using the appropriate formulas, find the mean and the standard deviation of the sampling distribution of the sample proportion. a. For a random sample of size n=4000. b. For a random sample of size n=1000. c. For a random sample of size n=250.
Lesson 6.2.4: Binomial Distribution and Sample Proportions A sample proportion, such as the one computed in Question 4, is equal to a number of successes (x), divided by the sample size (n). The notation for a sample proportion is p, and it is computed by the formula p = Each value of x corresponds to a unique sample proportion ( p ), as computed by this formula. For example, x = 1 implies p = + - 0.10. These events,...
