Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the given level of significance alphaα using the given sample statistics. Claim: p ≠0.28; α equals=0.05; Sample statistics: p̂=0.27, n=200 1) Find the z-test statistic. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. z= ??? 2) Fail to reject or reject the hypothesis??? and why??? Thank you!!

When you conduct a significance test, what does the probability value tell you, exactly? the probability of replication the probability of observing a trend this extreme or more, assuming the null hypothesis is true the probability that the alternative hypothesis is true the probability that the null hypothesis is true the probability that the null hypothesis is false the probability that the alternative hypothesis is false

Suppose that you wish to test a claim about a population mean. Which distribution should be used given that the sample is a simple random sample, σ is not known, n = 15 and the population is normally distributed? The z-distribution The t-distribution The Chi-Square Distribution The F-distribution A hypothesis in statistics is a claim or a statement about a sample statistic population parameter legitimate inheritance weather conditions A market researcher selects every 40th student from a group of 500...

Why is the Central Limit Theorem useful? [Q8P5.3] a. Because when the conditions for the CLT are met, it allows us to use a Normal distribution to approximate the distribution of the whole population, even if we don't know whether the population follows a Normal distribution. Because when the conditions of the CLT are met, it allows us to calculate the area in the tails of the population distribution and therefore the probability of obtaining an observation as or more...

2. (2 True-False. Just say whether each statement is True or False – no need to justify your answer. 1. If the number of trials in the binomial distribution increases by 1 (and P equals .50), the probability of getting either of the most extreme possible outcomes (that is, 0 or N) is cut in half. 2. If the number of trials in the binomial distribution increases by 1 (and P does not equal .50), the probability of getting either of...

When should I use the Paired t-test? Remember that some tests, such as chi squared, can be used under various circumstances. The goal of the test changes based on the situation. Pay attention to the specific conditions noted in parenthesis to ensure you are picking the correct goal. A. Compare two treatments consisting of paired data where a normal distribution can be assumed B. Test the fit of the normal distribution to the data set. C. Compare two treatment groups...

Determine whether a normal sampling distribution can be used for the following sample statistics. If it can be used, test the claim about the difference between two population proportions p1and p2 at the level of significance α. Assume that the samples are random and independent. Claim: p 1 ≠ p2, α=0.01 Sample Statistics: x1=40, n1=69, x2=42, n2=59 Determine whether a normal sampling distribution can be used. 1) The samples are random and independent.
