3o) State the conclusion based on the Hypothesis Tests conducted at 0.02 level of significance

4j) Conduct the p-value based hypothesis test on the statistical significance of linear regression between the dependent variable and all the independent variables (together) at 0.03 level of significance. What is the decision based on the Hypothesis Test?

Biology ROCKS!

A species of bird removes parasites from a large mammal. However, if parasite numbers are low, the bird sometimes pecks at healthy tissue to obtain food.  (Over time, the damage caused outweighs the benefit of parasite removal.)

3j) Based on the Regression report, what is the correct p-value (rounded to 4 digits after the decimal) to be used to test for the Statistical Significance of Linear Regression between the variables?

Two species of coral reef fish clean parasites from larger fish. The cleaner fish obtain food, and the larger fish experience improved health.

3i) The correct Alternative Hypotheses in the Hypothesis test for the statistical significance of Linear Regression between the variables is:

3q) What is the sample correlation coefficient (rounded to 4 digits after the decimal) between the two variables: Years in Service and Annual Maintenance Cost ($1000s)

3d) The DEPENDENT VARIABLE in this Problem is:

A study was conducted to understand how American college students manage their finances. Each person in a representative sample of 600 college students was asked if they had one or more credit cards. If so, whether they paid their balance in full each month. There were 400 who did not pay balance in full each month. For this sample of 400 students, the sample mean credit card balance was reported to be $850. For purposes of this exercise, assume population standard deviation is $250. Is there convincing evidence that college students who do not pay their credit card balance in full each month have a mean balance that is greater than $820 at 0.02 level of significance? 1q) What is your Hypothesis Test Decision under the p-value approach and why?
