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...

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...

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...
