An agency reports that 11.2% of workers in a particular country belonged to unions. Suppose a sample of 400 workers is collected to determine whether union efforts to organize have increased union membership. (a)Formulate the hypotheses that can be used to determine whether union membership has increased.

A national magazine stated that at most, 20% of millennials have a pool membership. Formulate an appropriate one-sample test of hypothesis to test this. Determine the null hypothesis, Ho, and the alternative hypothesis, H. Ho H (Type whole numbers.) A bank found that in recent years, the average monthly charge on its credit card was $1,350. With an improving economy, they suspect that this amount has increased. A sample of 45 customers resulted in an average monthly charge of $1,375.09...

Hypotheses and summary sample statistics are given for a test for a proportion. Test Ho : p = 0.3 vs Ha :p>0.3 when the sample has p = 0.37 and n = 500. Find the value of the standardized z-test statistic and then use the standard normal distribution to find the p-value. Round your answers to three decimal places. z-test statistic - p-value = What is the conclusion using a 5% significance level? O Reject Ho O Do not reject...

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 α using the given sample statistics. Claim: p < 0.12; α-0.10; Sample statistics: p-0.08, n-25 Can the normal sampling distribution be used? O A. No, because np is less than 5. O B. Yes, because pq is greater than α = 0.10 C. No, because nq is less than 5. O D....

An official of a large national union claims that the fraction of women in the union is not significantly different from 58%. To test this claim, a random sample of 400 individuals in the union is taken. Of those 400,215 are women. Use the p-value to conduct the hypothesis test and use a =0.05 level of significance. p-value = 0.0446 <0.05; Fail to reject H. - O a. p-value = 0.0446 <0,05; Reject H.
