A large chemistry course took their final exam. The mean was 75 with a standard deviation of 8. What are the exam scores that separate the top and bottom 5 percent of the class (extreme 10%) 2. What are the exams scores that separate the middle 10% of the class (5% on each side of the mean)? Use table below and draw normal distribution
normal distribution with a mean of u = 23.8 in, and a standard deviation of a = 1.1 in. These data are often used in the design of different Suppose that the sitting back-to-knee length for a group of adults has seats, including aircraft seats, train seats, theater seats, and classroom seats. Instead of using 0.05 for identifying significant values, use the criteria that a value x is significantly high if P(x or greater)50.01 and a value is significantly low if P(x or less) s0.01. Find the back-to-knee lengths separating significant values from those that are not significant. Using these criteria, is a back-to-knee length of 26.0 in. significantly high? Find the back-to-knee lengths separating significant values from those that are not significant. Back-to-knee lengths greater than in. and less than (Round to one decimal place as needed.) in. are not significant, and values outside that range are considered significant. Using these criteria, is a back-to-knee length of 26.0 in.…

Impact of the Population Standard Deviation on SE Compute the standard error for sample means from populations all with mean μ = 80 and with standard deviations o and o = 75 using a sample size of n = 90. Round your answers to two decimal places, if necessary. Standard Deviation o = 11: o = 40: o = 75: HI Standard Error = 11, o = 40,
Making auto parts A grinding machine in an auto parts plant prepares axles with a target diameter 40.125 millimeters (mm). The machine has some variability, so the standard deviation of the diameters is o = 0.002 mm. The machine operator inspects a random sample of 4 axles each hour for quality control purposes and records the sample mean diameter r. Assuming that the process is working properly, what are the mean and standard deviation of the sampling distribution of x? Explain. Making auto parts Refer to Exercise 50. How many axles would you need to sample if you wanted the standard deviation of the sampling distribution of x to be 0.0005 mm? Justity your answer.
The test scores for the analytical writing section of a particular standardized test can be approximated by a normal distribution as shown in the figure (a) What is the maximum score that can be in the bottom 15% of scores ? (b) Between what two values does the middle 70% of scores lie?
Medical Operations The director of a medical hospital feels that her surgeons perform more operations per year than the national average of 211. She selected a random sample of 15 surgeons and found that the mean number of operations they performed was 213.2. The standard deviation of the sample was 3.8. Is there enough evidence to support the director's feelings at =α0.05? Assume that the population is approximately normally distributed. Use the critical value method and tables. State the hypotheses and identify the claim. H0: Is a claim or not a claim H1: is a claim or is not a claim Find the critical value: Compute the test value: Make the decision Summarize the results. There is or is not enough evidence to support the claim.
