Your assessment must be submitted using this template. Feel free to add additional work at the bottom, but the top must remain. There are five tables in this worksheet: two for statistical summary, two for confidence intervals, and one for hypothesis tests. To find a table quickly, press Ctrl+G. Press the Tab key to move to input areas of the table. Note: See the worksheet named "Example" (in the bottom tab) for examples of how to fill in the yellow boxes. Blank row, Table 1 begins in A8.

Two-tailed test, reject Ho when z < -1.96 or z > 1.96. End of worksheet.

Conclusion We are 95% confident the true population proportion is between 0.316 and 0.584. We are 95% confident the true population proportion is between 0.335 and 0.605. We are 95% confident the true population proportion is between 0.375 and 0.645. We are 95% confident the true population proportion is between 0.355 and 0.625. Conclusion We are 95% confident the true population proportion is between 36380.672 and 43 We are 95% confident the true population proportion is between 22.717 and 26.083 Test Statistic Decision Summary -0.741619848709566 Do not Reject Ho There is not sufficient statistical eviden -0.444971909225739 Do not Reject Ho There is not sufficient statistical eviden 0.148323969741913 Do not Reject Ho There is not sufficient statistical eviden -0.148323969741913 Do not Reject Ho There is not sufficient statistical eviden 0.097812668782759 Do not Reject Ho There is not sufficient statistical eviden 1.66389068620736 Do not Reject Ho There is not sufficient statistical eviden and Ha.
