Transcribed Image Text:Suppose 400 random samples (each of size 25) are drawn from a population of male adults whose weights are approximately Normally distributed with mean 178.3 lb and standard deviation 7.8 lb. Sample means are recorded to the
nearest 0.1 lb.
Click here to view page 1 of the standard normal distribution table.
Click here to view page 2 of the standard normal distribution table,
(a) The expected value and standard deviation of the sample mean X is µy = and oz = |
, respectively.
(Type an integer or a decimal. Do not round.)
(b) It can be expected that sample means fall between 176.2 lb and 179.7 Ib, both inclusive (2 and s).
(Round to the nearest integer.)
