Hi I need help on these questions.

Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.) t = 21.38 X P-value = 0 X State the conclusion in the problem context. O Reject Ho. This model is useful. O Fail to reject Ho. This model is useful. O Reject Ho. This model is not useful. O Fail to reject Ho. This model is not useful. How much of the variation in y can be explained by its relationship with In(x)? (Round your answer to one decimal place.) % Predict amplitude when cycles to failure = 4000. (Use a 95% prediction interval. Round your answers to five decimal places.) -5.02220 X -3.06858 XFailures in aircraft gas turbine engines due to high cycle fatigue is a pervasive problem. An article gave the accompanying data and fit a nonlinear regression model in order to predict strain amplitude from cycles to failure. (Use a = 0.05.)
