For this stream, narrow channel width is a good indicator that erosion is not occurring. An independent random sample of widths from 10 locations is collected and we can assume a normal distribution. Test the claim that the mean width of ten locations within the stream is more than 3.5 meters. Show your work. Use a .05 significance level and the following sample data: 2.3 5.3 3.5 4.9 4.5 4.1 4.1 5 7.3 6.2 The sample standard deviation is 1.4 (hint: you need to calculate x-bar) Complete the following questions. 1. What are the null and alternative hypotheses. 2. Calculate the test statistic. 3. What is the level of significance? 4. The p-value is 0.035. What is your decision about the null hypothesis? 5. What is your conclusion? Click Save and Submit to save and submit. Click Save All Answers to save all answers. Save All Answers Save and
