Question 489207: If anyone can help me with these questions I would really appreciate it!!!!
Using the r calculated in problem 2c test the significance of the correlation coefficient using = 0.01 and the claim rho 0. Use the 7-steps hypothesis test shown at the end of this project
1. H0:
Ha:
2. = 0.01
3.
4. the critical value(s) t0
5. Rejection region:
6. Decision:
7. Interpretation:
Guidelines -- Hypothesis Testing Steps:
1. State H0 and Ha.
2. Specify the level of significance alpha .
3. Find the test statistic using the given data.
4. Find the critical value(s) t0. Use the method specified in the problem statement.
5. Define the rejection region using critical value(s)
6. Make a decision to reject or fail to reject the null hypothesis.
7. Interpret the decision in the context of the original claim.
4. The data below are the gestation periods, in months, of randomly selected animals and their corresponding life spans, in years.
Gestation, x 8 2.1 1.3 1 11.5 5.3 3.8 24.3
Life span, y 30 12 6 3 25 12 10 40
a. Find the equation of the regression line for the given data. Round the line values to the nearest two decimal places. (4 points) Show your work or the Excel output.
b. Using the equation found in Part a, predict the life span when the gestation is 10 months. Round to the nearest absence
