(2) 1. Can the null hypothesis or the alternate hypothesis state that the mean of the population is equal to a value? Explain.

(2) 2. If the null hypothesis is that the mean is less than or equal to 4, what is the alternate hypothesis?

(2) 3. What is the power of the test? Explain what beta is.

(2) 4. Explain the difference between a type I and a type II error.

(2) 5. Can you use both Tchebysheff's Rule and the Empirical Rule for flat data? Why or why not?

(2) 6. Suppose I have flat data with a mean of 14 and a standard deviation of 2. What can you tell me about the data between 12 and 16?

(2) 7. Suppose I have mound-shaped data that is symmetrical with a mean of 14 and a standard deviation of 2. What can you tell me about the data between 10 and 14?

Researchers examined the effect of phosphate supplementation on bone formation in six healthy adult dogs. For each dog, bone formation was measured twice: once after 12 weeks of phosphate supplementation and once after a 12-week control period. The results in percent bone growth are shown below. Do the data provide evidence that phosphate supplementation significantly stimulates bone formation?...
