PLEASE ANSWER CLEARLY
The national figure for the percent of Americans on welfare is around 20%. In Lucas County, a random sample of 285 people found that 68 of them are on welfare. Suppose the claim the proportion of all people in Lucas County that are on welfare is greater than the national figure of 20%" is tested and resulted in not rejecting the null hypothesis. The 95% confidence interval is: One sample proportion summary confidence interval: P: Proportion of...

In the picture below, I have the output for the same two sets of data. I ran the hypothesis test and the confidence interval. If you had a choice to use one output or the other, which would you choose and why? Make sure to be specific and include what information you get from each and what information you don't get if you use one over the other. Options Two sample T summary hypothesis test: : Mean of Population 1...

1.(10) Assume that the proportion of successes in a population is p. If simple random samples of size n are drawn from the population and the proportions, p. of successes in the samples are calculated, then the distribution of the sample proportions p is normal. What are the mean and standard deviation of this Normal distribution? Hp = 2.(10) How large do the number of successes and the number of failures in a sample have to be in order to...

Assume that a sample is used to estimate a population proportion p. Find the 95% confidence interval for a sample of size 155 with 20 successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. 95% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
