What is z value for 90 percent confidence interval estimation?
The answer will depend on whether the interval in one or two sided. One-sided: Z < 1.28 or Z > -1.28 Two-sided: -1.64 < Z < 1.64
Why you use always 95 percent confidence interval?
You don't. There are times when you use 99% or 99.5%, and others where you will settle for 90%. The percentage chosen will depend on the implications of making the wrong decision.
Twenty five percent of nintey?
90 is 100 percent. 90/100 = 0.9 is 1 percent. This value times 25 gives you 25 percent. Solution: 22.5
What does CL mean in mathematical terms?
It may stand for the number 150 (Roman numbers). In statistics, CL usually refers to "Confidence Level," which establishes a likelihood (typically 90 or 95%) an estimated value will fall within a given Confidence Interval (a range of estimated values). For example... [I'll get more done on this later]

How should I construct a confidence interval for the population proportion p with n equals 144 and x equals 82 with a 90 percent confidence level?
The confidence interval will be Pi+-z*spz5%= 1.6449Pi = x/nSp = Sqrt(Pi(1-Pi)/n)Pi ~= 0.5694Sp = Sqrt(.5694*0.4306/144) ~= 0.0413Pi - 0.0679 < p < Pi + 0.06790.5016 < p < 0.6373You can do this on your TI-83/84 with 1-PropZInt (Stat->Tests->A)
What is 90 percent of 2 kilometers?
To find 90 percent of a value, multiply the value by 0.9. In this instance, 0.9 x 2 = 1.8 kilometres.
What is the value of 10 percent of 90 plus 90 percent of 10?
10% of 90 = 990% 0f 10 = 9(10% of 90) + (90% of 10) = 18
