A hypothesis testing was performedto decide if the sample data support the claim. Ho: support the claim. Ha: opposite to the claim. This is Left-Taled test with the significance level 10% (0.10). Calculated z-value for test statistics is z = - 0.45. Does the sample data support the claim? Based on this sample, should we reject or do not reject Ho? Tips: 1) Use Appendix Table for Normal Distribution and find at what z area to the left under Standard Normal Distribution curve is close to 0.10. 2) That z will be critical value. Rejection region is to the left of that z. Draw the number line for z, mark position of z_crand shade the rejection region. 3) Find position of the given z-value of sample statistics on this number line. Make your desision Reject or Do Not Reject Ho.
