Consider the data given on the website, obtained in a simple linear regression analysis.
a. Find the estimated regression line, and complete the summary ANOVA table. Conduct an F test for a significant regression. Use a significance level of 0.01.
b. Find s, an estimate of the standard deviation.
c. Find a 95% prediction interval for an observed value of Y when x = 37. Based on this interval, do you think it islikely that an observed value of Y (for x = 37) will be greater than 170? Justify your answer.
What kind of sampling design is his staff planning to use?- What difference would you expect the poll to show?-Could the campaign be misled by the poll, concluding that there really is no gender gap? Explain.
What deccision should be made about the null hypothesis, and what decision should be made about the effect of the program.
Consider the vector X in Problem 5.7.1 and define the average to be Y = (X1 + X2 + X3)/3. What is the probability that Y > 4? In this problem, we extend the proof of Theorem 5.16 to the case when A is m × n with m X = 0.
At the 5% level of significance, can we infer that the difference in the level of satisfaction with service between the two branches is wider than 5 p.c. points?
Level of education attained by the women from a rural region is divided into three categories: can read/write degree; primary degree; secondary and above degree
If 100 chips are randomly selected, what is the expected number of defective ones? What is the standard deviation of the number of defective chips?
A sample of 40 observations is selected from one somewhat normal population. The sample mean is 102 and the sample standard deviation is 5.
Design an op-amp circuit to provide an output vO = -[2v1 + (v2/2)]. Choose relatively low values of resistors but ones for which the input current (from each input signal source) does not exceed 50 μA for 1-V input signals.
What is the probability of a randomly selected student having devoted no more than 8 hours to studying for the exam? What is the probability of a randomly selected student having earned an A or a B on the exam, given they devoted no more than 8 hou..

At a certain university, the average cost of books per student was 400.00 last semester. In a sample of 40 students this semsester, their average cost was 340.00 with a standard deviation of 80.00.
with loss function L(θ,a)= w(θ)(θ-a)^2, where w(θ) is a fixed weighted function. Determine the Bayes rule and comment on the role of w(θ) in this problem.
