- 7.20 a If U has a x² distribution with v df, find E(U) and V (U). b Using the results of Theorem 7.3, find E(S2) and V (S2) when Y₁, Y2,..., Y, is a random sample from a normal distribution with mean μ and variance o².arrow_forwardAccording to a survey conducted by the American Bar Association, 1 in every 410 Americans is a lawyer, but 1 in every 64 residents of Washington, D.C., is a lawyer. a If you select a random sample of 1500 Americans, what is the approximate probability that the sample contains at least one lawyer? b If the sample is selected from among the residents of Washington, D.C., what is the ap- proximate probability that the sample contains more than 30 lawyers? c If you stand on a Washington, D.C., street corner and interview the first 1000 persons who walked by and 30 say that they are lawyers, does this suggest that the density of lawyers passing the corner exceeds the density within the city? Explain.arrow_forward7.50 Shear strength measurements for spot welds have been found to have standard deviation 10 pounds per square inch (psi). If 100 test welds are to be measured, what is the approximate probability that the sample mean will be within 1 psi of the true population mean? 7.51 Refer to Exercise 7.50. If the standard deviation of shear strength measurements for spot welds is 10 psi, how many test welds should be sampled if we want the sample mean to be within 1 psi of the true mean with probability approximately 992arrow_forward
- 8.12 The reading on a voltage meter connected to a test circuit is uniformly distributed over the interval (0, +1), where 0 is the true but unknown voltage of the circuit. Suppose that Y₁, Y2,..., Y, denote a random sample of such readings. a Show that Y is a biased estimator of and compute the bias. b Find a function of Y that is an unbiased estimator of 0. C Find MSE(Y) when Y is used as an estimator of 0.arrow_forwardA survey finds that 60% of people prefer coffee over tea, and 30% prefer both coffee and tea. What is the probability that a randomly chosen person prefers at least one of the two drinks? Define the following events: • A: Preferring coffee. • B: Preferring tea.arrow_forward2. After an earthquake, each building in a community can be classified based on the ground shaking it experienced (Low level of shaking SL; Moderate level of shaking Sм; High level of shaking SH) and the damage it experienced (No damage DN; Moderate damage Dм; Severe damage Ds). a. Write the sample space of possible building classifications for a given building. b. Define the event that a building experiences at least some damage. C. Define the event that a building experiences at least moderate shaking but no damage.arrow_forward
- b. According to the analyst, what is the probability that the confidence score is not 1? 11. Professor Sanchez has been teaching Principles of Economics for over 25 years. He uses the following scale for grading. Grade Numerical Score Probability A 4 0.10 B 3 0.30 C 2 0.40 D 1 0.10 F O 0.10 a. Depict the probability distribution graphically. Comment on whether or not the probability distribution is symmetric. b. Convert the probability distribution to a cumulative probability distribution. C. What is the probability of earning at least a B in Professor Sanchez's course? d. What is the probability of passing Professor Sanchez's course? 2. Professor Khurana expects to be able to use her grant money to fund up to two students for research assistance. While she realizes that there is a 5% chance that she may not be able to fund any student, there is an 80% chance that she will be able to fund two students. a.

- The same final exam of the astronomy course was given to two groups of students. The maximum number of points that a student can score is 100. The first group consisted of a random sample of 10 students who were taught by Professor A. Students from the first group obtained the following results: 87 88 91 88 86 92 81 93 73 99 The second group consisted of a random sample of 9 students who were taught by Professor B. Students from the second group obtained the following results: 74 74 79 97 67 88 86 83 78 Compute the mean squares of between-group variability, MSBET.
