Suppose that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of u = 22.7 in. and a standard deviation of o = 1.2 in. These data are often used in the design of different 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)s0.01 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 25.0 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 in. are not significant, and values outside that range are considered significant. (Round to one decimal place as needed.) Using these criteria, is a back-to-knee length of 25.0 in.…

The birth weight of newborn babes (measured by O'Cathain et al, 2002 n = 3226) is approximately normally distributed with a mean of 3.39kg and standard deviation of 0.55kg. Rounded to three decimals, What weight does a baby have to have to be in the 97%?
A credit card company claims that the mean credit card debt for individuals is greater than $5,000. You want to test this claim. You find that a random sample of 27 cardholders has a mean credit card balance of $5,199 and a standard deviation of $575. At α=0.05, can you support the claim? Complete parts (a) through (e) below. Assume the population is normally distributed.
A medical company pack medication in bags marked as 250 gA large number of packs of medication were weighed and the mean and standard deviation were calculated as 255 g and 2.5 g respectively.Assuming this data is normally distributed, what percentage of packs are underweight? Develop a Standard Normal Distribution curve.
Suppose that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of μ = 23.7 in. and a standard deviation of o=1.1 in. These data are often used in the design of different 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) ≤ 0.01 and a value is significantly low if P(x or less) ≤0.01. 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 25.8 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 in. are not significant, and values outside that range are considered significant. (Round to one decimal place as needed.) rect: 0
