A consumer electronics company is comparing the brightness of twodifferent types of picture tubes for use in its television sets. Tube type Ahas mean brightness of 100 and standard deviation of 16, and tube typeB has unknown mean brightness, but the standard deviation is assumedto be identical to that for type A. A random sample of n = 25 tubes ofeach type is selected, and Xpar B – XbarA is computed. If ug equals orexceeds uA, the manufacturer would like to adopt type B for use. Theobserved difference is xhar B - Ibar A = 3.5. What decision would youmake, and why?

The breaking strengths of cables produced by a certain manufacturer have historically had a mean of 1775 pounds and a standard deviation of 70 pounds. The company believes that, due to an improvement in the manufacturing process, the mean breaking strength, u, of the cables is now greater than 1775 pounds. To see if this is the case, 14 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1812 pounds. Assume that the population is normally distributed. Can we support, at the 0.10 level of significance, the claim that the population mean breaking strength of the newly- manufactured cables is greater than 1775 pounds? Assume that the population standard deviation has not changed. Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.)

Chicago area doctors are concerned about their female patients' systolic blood pressure since an above average to high blood pressure can be an indicator of heart disease or other serious conditions. The average systolic blood pressure for a Chicago woman is 135mmHg , with a standard deviation of 7.5mmHg. Suppose a random sample of 100 women is selected. Identify each of the following:

The lecturer are concerned that students who enrolled for the course this semester are spending more time playing online games than revising for their upcoming test. In order to pass the test, students need to spend at least 6 hours per week on the course materials. They conducted a survey of 120 students from Section 10G and 15P for which the result shows that the mean time they spent studying for the course in a week is 5.7667 hours with a standard deviation of 1.6487 hours. Using the critical value z0.025 =1.96 , perform hypothesis testing for mean to test whether or not students spent at least 6 hours weekly to study for the course.

A manufacturer creates and sells an electronic product that uses one resistor. The product will be defective if its resistor has a resistance below 180 ohms. The manufacturer purchases 1,000 resistors from a new supplier. The supplier claims that the average resistance of their resistors is 200 ohms with a standard deviation of 10 ohms. a. The manufacturer decides to randomly sample n = average resistance is really 200 ohms. If the estimated average resistance is below 190, the shipment will be sent back. Assuming that the suppliers specifications are correct, what is the probability that the shipment is sent back? (I.e. calculate P(X < 190).) Be sure to state any additional assumptions that you make, if any, to arrive at your answer. b. If the supplier's specification is true and the shipment of resistors is used by the manufacturer, what is the probability that a created product will be defective? State any assumptions needed to arrive at 4 of the resistors from the batch to check…

The breaking strengths of cables produced by a certain manufacturer have historically had a mean of 1775 pounds and a standard deviation of 70 pounds. The Español company believes that, due to an improvement in the manufacturing process, the mean breaking strength, µ, of the cables is now greater than 1775 pounds. To see if this is the case, 16 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1806 pounds.

The salaries of professional football players are also heavily skewed right with a mean of $1.9 million and a standard deviation of $1.5 million. A random sample of 40 baseball players’ salaries and 35 football players’ salaries is selected. The mean salary is determined for both samples. Let represent the difference in the mean salaries for baseball and football players. Which of the following represents the shape of the sampling distribution for ? skewed right since the populations are both right skewed skewed right since the differences in salaries cannot be negative approximately Normal since both sample sizes are greater than 30 approximately Normal since the sum of the sample sizes is greater than 30
