A turtle believes that the number of pellets he receives at each meal is approximately normal with unknown mean and variance. Data from the previous 24 meals yields a sample mean of 6.79 and sample standard deviation of 0.66.

5. He suspects that he is receiving less than 7 sticks per meal, on average. Is there enough evidence, at significance level ? = 0.05, to support his suspicion? Also, give a range for the p-value of the test.

6. Further, the turtle suspects that the standard deviation of the number of sticks he receives per meal is greater than 0.5. Is there enough evidence, at significance level ? = 0.01, to support this suspicion? Also, give a range for the p-value of the test.

A local tire dealer wants to predict the number of tires sold each month. He believes that the number of tires sold is a linear function of the amount of money invested in advertising. He randomly selects 6 months of data consisting of tire sales (in thousands of tires) and advertising expenditures (in thousands of dollars). Based on the data set with 6 observations, the simple linear regression model yielded the following results. ?X =24 ?X2=124 ?Y  = 42 ?Y2 =338...

Many variables in medicine follow a normal distribution where there are approximately an equal number of values below the mean as above the mean. Describe two variables that would probably follow a normal distribution. Also note which of the two variables would be likely to have a larger standard deviation and why. As an alternative question, what are some other potential probability distributions in the health care field such as bimodal, skewed, or exponential and give variables that would probably...

A gambler tosses a coin and a tetrahedron at each stage. If "H", he receives the amount appearing at the face of the tetrahedron. If "T", he pays the amount. The tetrahedron is fair, but the probability of H is ⅔. The game ends if the gambler reaches 0 or less wealth, or accumulates 6 or more wealth. Define X_n = 0 if wealth is less than or equal to zero. Define X_n = i if wealth is i =...
