WebAbstract: Interval training refers to an intermittent style of exercise, in which bouts of more intense effort are interspersed with recovery periods within a given training session. … WebIn developing an interval estimate for a population mean, a sample of 40 observations was used. The interval estimate was 28 ± 1. Had the sample size been 160 instead of 40, the interval estimate would have been: A) 28 ± 0. B) 28 ± 0. C) 28 ± 1. D) 28 ± 2.

Web26 mrt. 2024 · Construct a 95 % confidence interval for the population mean, and interpret its meaning. Solution Since the population is normally distributed, the sample is small, and the population standard deviation is unknown, the formula that applies is Equation 7.2.1. Confidence level 95 % means that α = 1 − 0.95 = 0.05 so α / 2 = 0.025.
