The mean of 25 observations is 27
Splet1 answers. Yogita Ingle 2 years, 4 months ago. Mean of given observations = sum of given observations/ total number of observations. Mean of 25 observations = 27. ∴ Sum of 25 observations = 27 × 25 = 675. If 7 is subtracted from every number, then the sum = 675 – (25 × 7) = 675 – 175 = 500. Then, new mean = 500/25 = 20. SpletShort Answer If a random sample of 25 observations is taken from the normal distribution with mean μ and standard deviation 2, what is the probability that the sample mean will lie within one unit of μ ? Probability that the sample mean will lie within one unit of μ is 0.9876. See the step by step solution Step by Step Solution TABLE OF CONTENTS
