Mercury in Tuna - Mercury, if ingested can cause severe health problems. Theamount of mercury in Tuna's body tissue is much higher than other fish.It is known that the amount of mercury in Albacore tuna is normally distributed withmean 10.13 micrograms and standard deviation of 2.03 micrograms per ounce.A food company has a production line for canned albacore tuna. They regularly takerandom samples of 10 cans of tuna and test the amount of mercury. If the samplemean amount of mercury in tuna exceeds 12 micrograms per ounce, the productionline will be stopped to find the source of contamination.Let u denote the actual population mean amount of mercury in tuna per ounce. Thehypotheses for this testing situation are:Но : и 3D 10.13 vs HA : и > 10.13.10.13 vs HA: H > 10.13.To calculate the chance of making a Type I error using the decision rule above, whatwould you use as the mean for the normal distribution in your graphing calculator?Your Answer:

Any assumption about the parameter or probability function is called hypothesis testing. There is…

Weights of one-year-old male German Shepherd dogs have a standard deviation of 1.5 lbs. Determine the percentage of all samples of 200 one-year-old male German Shepherds that have mean weights within 0.125 lb of the population mean weight of all one-year-old German Shepherds.
The lifetimes of a certain type of calculator battery are normally distributed. The mean lifetime is 400 days, with a standard deviation of 50 days. For a sample of 6000 new batteries, determine how many batteries will last less than 280 days.
Steel rods are manufactured with a mean length of 25 centimeters. Because of variability in the manufacturing process, the lengths of the rods are approximately normally distributed with a standard deviation of 0.08cm. Any rods that are shorter than 24.81cm or longer than 25.19cm are discarded. What proportion of the rods will be discarded?
The admission committee of AUCA passes 33% of those who took the exam. If the scores follow a normal distribution with a mean of 85 and a standard deviation of 9, what is the passing score?
Low‑density lipoprotein, or LDL, is the main source of cholesterol buildup and blockage in the arteries. This is why LDL is known as "bad cholesterol." LDL is measured in milligrams per deciliter of blood, or mg/dL. In a population of adults at risk for cardiovascular problems, the distribution of LDL levels is normal, with a mean of 123123 mg/dL and a standard deviation of 4141 mg/dL. If an individual's LDL is at least 11 standard deviation or more above the mean, he or she will be monitored carefully by a doctor. What percentage of individuals from this population will have LDL levels 11 or more standard deviations above the mean? Use the 6868–9595–99.799.7 rule. (Enter your exact answer as a whole number.)
The gas mileage for a new model of car is normally distributed, with a standard deviation of 3.5 miles per gallon. If only 4% of the cars have a gas mileage of above 20 mpg, what is the mean of the distribution
Aldo, a highway safety inspector, is concerned about the potential for accidents caused by boulders that fall down a sandstone cliff beside a main highway. As part of an accident simulator, Aldo models the boulders' weights using a normal distribution with a mean of 556 kg and a standard deviation of 100 kg find the percentage of boulders that weigh less than 520kg or more than 592kg according to the model. .
The average high-density lipoprotein (HDL) cholesterol level of adult females is 53 milligrams per deciliter. You want to determine whether the true mean female HDL cholesterol level is more than the average. You decide to pull a random sample of 12 adult females and measure their HDL cholesterol level. You find the sample mean is 54.1 milligrams per deciliter and the standard deviation is 1.78 milligrams per deciliter. What are the test statistic and the p-value? O The test statistic is 2.14 and the p-value is 0.0278. O The test statistic is 0.0278 and the p-value is 2.14. O The test statistic is 1.1 and the p-value is 0.0278. O The test statistic is 0.0278 and the p-value is 1.1. O The test statistic is 0.51 and the p-value is 2.14.
