Objective: This activity has the purpose of helping students to compute the condence interval level and the size of a sample {Objective 1 and 2). Student Instructions: This assignment has a value of 10 points. You will have two (2} questions to answer and one (1} attempt to send this assignment. Refer to the calendar in Blackboard for due dates. Your calendar is available under the Tools menu > Calendar. Once you have answered all the questions you have to send the work the Attach File function in Black Board to attach your document and send it to the professor. To use the Attach File enter the Course Content in Black Board. Select the Assignment Module 9. attach the le and submit. Compute the condence interval and the sample size to compute the confidence interval and the sample size you should vary the condence level and the accuracy of the textbook example of the mean burn of the sample of propellants. Remember that in the textbook example if the a? = 51.3 n was equallp 25 propellants. o= 0.05 221: 20.05 = $1.95 o=2cmtsecond Let change :1 = 0.01, and the othervariables remain the same. The new accuracy is 0.01 cmlsec. Questions: 1 If you change the alpha from 0 05 to an alpha aft) 01 the condence level limits are smaller? 3. True 0. False 2. If you change the accuracy levelfrom 0.1 cmr'secto 0.01 cmlsec the sample sizeis bigger? a. True I). False
