- What is a sample space?The Wisconsin Fish and Game Department stocked a lake with 30% catfish, 15 % bass, 40% bluegill, and 15% Northern Pike. Five years later they took a random sample of 500 fish from the lake and found 120 catfish, 85 bass, 220 bluegill, and 75 Northern Pike. At the 5% level of significance, can we show that the distribution of fish changed over the 5-year interval? State and test appropriate hypotheses. State conclusions.Draw all possible sample of size n=2 without replacement from the population 3, 6,9,12 from a sampling distribution of the sample means. Hence state and verify the relation between Mean of sampling distribution of the mean and population mean; Variance of the sampling distribution of the mean and population variance.
- Following an oil spill, a particular region of the ocean is being tested for the level of a chemical called naphthalene. It is considered fact that fish from the region will be safe to eat if, and only if, the mean naphthalene level in the region is less than 3.3 parts per billion. A set of water specimens will be randomly selected from the region and tested, and if the results provide convinving evidence that the mean naphthalene level is less than 3.3, then the sale of fish from the region will be made legal. Which of the following describes a Type I error and its consequences? A) the authorities fail to obtain convincing evidence that the mean naphthalene level is less than 3.3, and do not legalize the sale of fish from the region when in fact the fish are SAFE for consumption. B) The definition of a Type I error depends on the actual results of the study in question C) The authorities fail to obtain convincing evidence that the mean naphthalene level is less than 3.3, and do not…A tire manufacturing company encourages its employees to promote a zero-accident environment by practicing safety measures. However, for the past year, there are 300 recorded accidents. The data below categorized these accidents according to the shift (morning, mid, and night) when it happened and the reason of the accident (dangerous conditions and employee error). For instance, 5% of the accidents occurred during morning shift for the reason of dangerous conditions. As an HR manager, you are tasked to select one incident at random as part of your presentation to newly-hired employees. Evaluate the probability of choosing an accident that happened during the mid shift knowing that the cause of the accident is due to dangerous conditions.A tire manufacturing company encourages its employees to promote a zero-accident environment by practicing safety measures.
