A factory produces steel cables, whose resilience follows a normal distribution of unknown mean and standard deviation σ = 10 KJ / m3. A sample of 100 pieces was taken and through a statistical study a confidence interval (898.04 - 901.96) was obtained for the average resilience of the steel cables produced in the factory. a) Calculate the value of the average resilience of the 100 pieces of the sample. b) Calculate the confidence level with which this interval has...

If the mesh tension of individual monitors follows a Normal distribution, we can describe capability by giving the percent of monitors that meet specifications. The old specifications for mesh tension are 100–400 mV. The new specifications are 150–350 mV. Because the process is in control, we can estimate that tension has mean 275 mVand standard deviation 38.4 mV (a) What percent of monitors meet the old specifications? (Enter your answer rounded to two decimal places.) percent of monitors: % (b)...

Power questions. Suppose a population follows a normal distribution with a standard deviation of 1. We take a random sample of n= 100 individuals from this population. We know, then, that sample mean for our population will have the property that X∼N(μ,1/100). (a)If μ= 10, find the probability that X >10.1645 (b)If μ= 10.3, find the probability that ̄X >10.1645 (c)Now, consider testing H0:μ= 10 vs H1:μ >10, using α= 0.05. What is the rejection rule for this test? Give...

Open the Excel program Suppose we want to know the standard normal distribution up to the given value. That is P(Z < a). Lets use Excel instead of the standard normal distribution table In cell A1 type mean. In cell B1 type 0. That means that we are letting mean be zero. click on cell A2 and type SD. In cell B2 type 1. That means that we are letting standard deviation be one. That is, the normal distribution is...

The distribution of weights for an industrial part appears to follow a normal distribution. You randomly selected 21 parts from a large batch of those parts, and determined the sample standard deviation = 4 g. If you want to test H0: σ2 = 16 versus Ha: σ2 ≠ 16, what is the absolute value of the test statistic you would use?
