Add that to our rep time of 3:19 to make 5:19 and we can calculate that 8 reps is 42:32; just right for our planned session.
Predict interval prediction

In statistical inference, specifically predictive inference, a prediction interval is an estimate of an interval in which a future observation will fall, with a certain probability, given what has already been observed. Prediction intervals are often used in regression analysis. Prediction intervals are used in both … See more For example, if one makes the parametric assumption that the underlying distribution is a normal distribution, and has a sample set {X1, ..., Xn}, then confidence intervals and credible intervals may be used to estimate the See more Given a sample from a normal distribution, whose parameters are unknown, it is possible to give prediction intervals in the frequentist sense, i.e., an interval [a, b] based on statistics … See more Contrast with confidence intervals Note that in the formula for the predictive confidence interval no mention is made of the unobservable … See more Seymour Geisser, a proponent of predictive inference, gives predictive applications of Bayesian statistics. In Bayesian … See more One can compute prediction intervals without any assumptions on the population; formally, this is a non-parametric method. If one has a sample of identical random variables {X1, ..., Xn}, then the probability that the next observation Xn+1 … See more Prediction intervals are commonly used as definitions of reference ranges, such as reference ranges for blood tests to give an idea of whether a blood test is normal or not.
