A marine equipment manufacturer has developed a new hydrophone line that the company claims has a mean 10 kilogram breaking force with a standard deviation of 0.5 kilograms. Check the hypothesis that μ = 8 kilograms is checked against the alternative that μ = 8 kilograms if a 50-line random sample is checked and a mean breaking force of 7.8 kilograms is observed. Using a 0.05 grade significance

A manufacturer of sports equipment has developed a new synthetic fishing line that the company claims has a mean breaking strength of 7.5 kilograms with a standard deviation of 0.7 kilogram. Test the hypothesis that µ = 7.5 kilograms, against the alternatives: (a) µ 6= 7.5; (b) µ > 7.5; (b) µ < 7.5. Given that a random sample of 50 lines is tested and found to have a mean breaking strength of 7.8 kilograms. Use a 0.01 level of...

A manufacturer of sports equipment has developed a new synthetic fishing line that the company claims has a mean breaking strength of 8 kg with a standard deviation of 0.5 kg. To test the claim, a random sample of 50 lines is tested and found to have a mean breaking strength of (7.8 kg) and a standard deviation of (0.7 kg).

A manufacturer has developed a new fishing line, which the company claims has a mean breaking strength of 14.5 kilograms with a standard deviation of 0.8 kilograms. Believing the mean breaking strength is less than what company has claimed, a customer protection agency took a random sample of 40 such fishing lines and found that the mean breaking strength for this sample is 13.2 kilograms. Given the breaking strength of all such lines have a normal distribution, test whether the...

A new chemical process has been developed for producing gasoline. The company claims that this new process will increase the octane rating of the gasoline. Sixteen samples of the gasoline produced with the new process are selected at random and their octane reading were: 94, 93, 97, 92, 96, 94, 95, 91, 98, 95, 92, 91, 98, 95, 92, 91, 95, 96, 97, 93. If the mean octane using the existing process is 93, is the company's claim correct (use 1%)...

8) A scientific supply company has developed a new breed of lab rat, which it claims weighs the same as the classic white rat. The population mean (and standard deviation) for the classic white rat is 485 grams (20 grams). A researcher obtained a sample of 76 of the new breed of rats, weighed them, and found M = 500 grams (SD = 12 grams). What test should he do to see if the company’s claim is true? Complete the...
