What was your error term in your confidence interval? At the same time, I assumed that the null hypothesis is true.Īccording to your analysis, what are the upper and lower limits of your confidence interval?įrom my analyzed results, the lower bound and the upper bound are 3.916861 and 28.377306 respectively. Another fact that makes the conditions satisfied is that the sample I used was independently selected. Notably, this condition is satisfied since the real size of the sample used is more than five thousand times while the sample size used is only thirty. In my case, since the samples were picked without returning or replacing, the population proportion should be more than ten times the samples taken (Berenson et al., 2012, p. From my samples, there were at least ten successes and eleven failures, which make my null hypothesis valid.
The sample was randomly selected from a population of over five thousand. In addition, it is appropriate according to consequential type I error.ĭo you think the conditions necessary to satisfy the hypothesis and confidential interval population proportion are met? Explain your answer.Īs per my random sample size of n equal to thirty (n = 30), there is a guarantee of normal population distribution. I used a significant level of 0.05 it coincides with the ninety-five percent interval. What is the significance level you are using? Give your reasons for using that level. At the same time, the region of rejecting the null hypothesis is only one end (Berenson et al., 2012, p. Since the inequality sign in the alternative hypothesis is ≠, the test used is right (an upper) or left (lower)-tail test. This has been evident in the manner of comparison of measurements from the data set.Īccording to you, did you use a two-tail test, right (an upper), or left (a lower)-tail test?
Which kind of sample test are you using between- sample test and two-sample test?Īccording to my analysis for the proportion of the clothesweek population, the one-sample test remains the applicable option. H A: μ 1 ≠10 cm the average proportion of clothesperweek is not ten centimeters.H o: μ 1 = 10 cm the average proportion of clothesperweek is ten centimeters.
