Question
**River Depth Hypothesis Testing** It is believed that the depth of a river is 15m, with a standard deviation (SD) of 1.6m. An engineer believes that this estimation is too low. She conducts 33 measurements and finds a mean depth of 15.8m. Test the hypothesis at the 94% confidence level. **Hypothesis Details:** - **Type of Test:** - A = Left-Tailed - B = Right-Tailed - C = 2-tailed - *(Choose one: ____)* - **Critical Values:** - *(Specify critical values, separated by a comma if there are two: ____)* - **Test Statistic:** - *(Calculate and enter the test statistic here: ____)* - **p-value:** - *(Determine and enter the p-value here: ____)* - **p-value Test Validity:** - *(Is the p-value test true or false? Type "true" or "false": ____)* This exercise involves testing a hypothesis regarding the mean depth of the river using statistical analysis. The critical values and test statistic will determine whether to accept or reject the hypothesis.
