ASSIGNMENT: At certain machinery shop, two machines are used to produced metal rods. A random sample of 11 rods from machine 1 showed a mean length of 5.95 inches with variance of 0.18 square inches while a random sample of 15 rods from machine 2 showed a mean length of 6.01 inches with variance of 0.2 square inches. Test whether there is a significant difference between the mean length of the two metal rods at a = 0.05.

The manager of a resort hotel stated that the mean guest bill for a weekend is $600 or less. A member of the hotel's accounting staff noticed that the total charges for guest bills have been increasing in recent months. The accountant will use a sample of future weekend guest bills to test the manager's claim. (a) Which form of the hypotheses should be used to test the manager's claim? Explain. Ho: u 2 600 HaiH 600 Но: и 3D 600 Ha: u + 600 The hypotheses Ho: µ 2 600 and H: µ 600 should be used because the accountant wants to test the manager's claim that the mean guest bill u is less than or equal to 600 and find evidence to support u > 600. The hypotheses Ho: u = 600 and H: µ + 600 should be used because the accountant wants to test the manager's claim that the mean guest bill u is equal to 600 and find evidence to support u + 600. (b) What conclusion is appropriate when H. cannot be rejected? We are not able to conclude that the manager's claim is wrong. We cannot conclude that u >…
You have determined that in the past three years there 7 of the 14 were hand injuries. Previous projections had indicated that under normal conditions, only four hand injuries were expected and 12 other injuries were expected. The remaining injuries were due to other causes. Calculate the chi-square value and discuss whether there was a significant difference in observed data vs. the expected data. Also discuss how the process of hypothesis testing might prove helpful o = 7 hand injuries and 7 other injuriese = 4 expected hand injuries and 12 other injuries
For the situation described below, state the null and alternative hypotheses to be tested. (Enter != for ≠ as needed.) A new variety of pearl millet is expected to provide an increased yield over the variety presently in use, which has a mean yield of about 55 bushels per acre.

The proportion of defective items is not allowed to be over 12%. A buyer wants to test whether the proportion of defectives in his shipment of 1000 items exceeds the allowable limit. The buyer takes a SRS of 100 items and finds that 19 are defective. State the null and alternative hypotheses for this test.

Please show as much work as possible, and please do not skip steps. I really want to learn how to solve this, so if you use a axiom please include it. Problem Statement: One out of every one- thousand people have disease X. A new test for X is available, but it's not very accurate. If you have X, there is an 80% chance the test comes back positive and a 20% chance it comes back negative. If you don't have X, there is a 60% chance the test comes back negative and a 40% chance it comes back positive. Question: You are randomly chosen to be tested for X. Since the test is not very accurate, you areadministered the test 10 times; assume the outcomes of these 10 tests are independent. Sevenout of the 10 tests come back positive. Given these test results, what is the probability youhave X?

If presenting results of a study regarding the cinquefoil of plant height of 3 plant gardens, contrast which statistical measures you have calculated are most effective at describing the height of these plants. Think about the pros and cons of each statistics measure, if you could only report 2 or 3 values, which would they be? Why?
