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...
A population proportion is 0.4. A sample of size 200 will be taken and the sample proportion will be used to estimate the population proportion. Use z-table. Round your answers to four decimal places. b. What is the probability that the sample proportion will be within ±0.06 of the population proportion?
A population proportion is 0.4 A sample of size 250 will be taken and the sample proportion will be used to estimate the population proportion. Use z-table. Round your answers to four decimal places. Do not round intermediate calculations. a. What is the probability that the sample proportion will be within +- .04 of the population proportion? b. What is the probability that the sample proportion will be within +- .06 of the population proportion?
Find the minimum sample size required to estimate a population proportion with a margin of error equal to .04 and a confidence level of 90%. A recent study resulted in a sample proportion of .70. ALSO determine the minimum sample size if no prior study was done.
The population proportion of success is 5% and the intended sample size is n=220n=220. Before drawing a sample from the population, you first want to describe the expected sampling distribution for the sample proprtion. Give answers in decimal format (as opposed to fractions or percentages). Give the mean for the distribution of sample proportions: μˆp=μp^= Give the standard deviation for the distribution of sample proportions: σˆp=σp^= Classify the shape of the distribution of sample proportions in this context: not normal nearly...
There are 200 data of 1 and 800 data of 0. Sample proportion is 0.4 Assume the population proportion is 0.2. You take a sample of 200. 1. Calculate the obtained z statistic. Find it on the output. 2. What is the probability of getting the sample proportion or less? Find it on the output. 3. Sketch the sampling distribution of the proportion that assumes the alternative hypothesis is true. Label: The expected proportion, observed proportion of your sample and...
Suppose that a population is asked whether they prefer soccer or another sport. Let p= 0.4 denote the proportion of the population that prefers soccer. Create a graphical summary of the population distribution. Suppose that a sample of size n=60, drawn from this population, contains 22 individuals that prefer soccer to other sports. Create a graphical summary of this sample data distribution. verify that the sampling distribution of sample proportions drawn from this population is approximately normal. Using p=0.4 and...
