The population mean and standard deviation are given below. Find the indicated probability and determine whether a sample mean in the given range below would be considered unusual. If convenient, use technology to find the probability. For a sample of nequals36, find the probability of a sample mean being less than 12 comma 750 or greater than 12 comma 753 when muequals12 comma 750 and sigmaequals1.7.

The sample mean would not be considered unusual because the probability is greater than or equal to 0.50 of the sample mean being within the range.                

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 12750

Standard Deviation, σ = 1.7

Sample size, n = 36

Formula:

Standard error due to sampling:

P(sample mean being less than 12,750 or greater than 12,753)

Thus, the sample mean would not be considered unusual because the probability is greater than or equal to 0.50 of the sample mean being within the range.
