###### Question:

ibuted Computea Confidence interval for the true proportion porty certainem (rounded to deci b. find the marginal error of the Confidence interval inquired to de e. We want to test if the true proportion porosity of a certain seam is more than 0.6. (wette enly the convenient sign) 1. Ho: Hy ii. Calculate and write the value of the test statistie: rounded to 2 decimale) W. Find the critical value for this test. Use 1% significance level i What is your conclusion? Une significance level Since the test statistic is less greater) evidence/don't have enough evidence of a certain seam is more than 5 te conclude that the proper d. How large the sample size is necessary if the marginal error of the interval is to be 00187
