The amount of pyroxidine (in grams) per multiple vitamin is normally distributed with a mean = 110 grams and a variance = 25 grams. A sample of 25 vitamins is to be selected. What is the probability that the sample mean will be greater than 100 grams?© BrainMass Inc. brainmass.com June 4, 2020, 1:26 am ad1c9bdddf
To find the probability of obtaining a given sample mean, we use the sampling distribution. Sampling distribution includes all the means of samples of size 25. The sampling distribution of means forms a normal distribution.
The mean of sampling ...
