Problems with Solutions. X is a normally distributed variable with mean μ = 30 and standard deviation σ = 4. Find the probabilities. a) P (X < 40) b) P (X > 21) c) P (30 < X < 35) A radar unit is used to measure the speeds of cars on a motorway. The speeds are normally distributed with a mean of 90 km/hr and a standard deviation of 10 km/hr.The confidence coefficient is simply the decimal form of the confidence level. So, for example, if the confidence level is 95%, the confidence coefficient is .95. The next step is to solve for α / 2. So, continuing with our example, we would have 1 - α = .95 and find the value of α / 2 to be .025. The most commonly used confidence level is ...Home » Mathematics Statistics and Analysis Calculators » Chi-Square Calculator. Chi-Square Calculator.

Formulas for critical values employ the quantile function of t-distribution, i.e., the inverse of the cdf:. Critical value for left-tailed t-test:The formula for the interquartile range is IQR = Q 3 - Q 1. Both the range and interquartile range are limited by the fact that they only use two values from the entire dataset. The variance is a measure of variability that uses all data values.
