WebNormal Distribution Table The table here shows the area from 0 to Z-value. Normal Distribution Problems and Solutions Question 1: Calculate the probability density function of normal distribution using the following data. x = 3, μ = 4 and σ = 2. Solution: Given, variable, x = 3 Mean = 4 and Standard deviation = 2 Webp-Values for the t Distribution – one tail, df = 19 f(t,df) 0 t-statistic t Area = p-value For two tails, multiply the value by 2, since the t PDF is symmetric. The p-value is the colored area under the t PDF in the sketch. Example: 1-tailed p at t = 1.06: p-value = TDIST(t,df,1) = 0.15122. 2-tailed p at t = 1.06: p-value = TDIST(t,df,2) = 0. ...
