What is t0=

what is p value=

In this study, a researcher investigates water clarity at a consistent location in a lake. The research involves recording measurements on identical dates over two separate years, spaced five years apart. The procedure utilizes a weighted disk painted black and white to measure the depth (in inches) at which it becomes invisible. The data collected is tabulated below: | Observation | 1 | 2 | 3 | 4 | 5 | 6 | |-------------|----|----|----|----|----|----| | Date | 1/25 | 3/19 | 5/30 | 7/3 | 9/13 | 11/7 | | Initial Depth, \( X_i \) | 65.9 | 74.2 | 70.7 | 66.6 | 69.8 | 50.3 | | Depth Five Years Later, \( Y_i \) | 73.4 | 73.5 | 65.4 | 70.4 | 76.7 | 52.0 | **Tasks:** - **a) Formulate the Null Hypothesis (\( H_0 \)) and Alternative Hypothesis (\( H_4 \)):** \((Type integers or decimals. Do not round.)\) - **b) Determine the test statistic for this hypothesis test:** \((Round to two decimal places as needed.)\) Instructions for students: Analyze the data to consider changes in water clarity over the five years, using appropriate statistical methods to test the stated hypotheses.
