The intelligence quotient (iq) test scores for adults are normally distributed with a population mean of 100 and a population standard deviation of 15. what is the probability we could select a sample of 50 adults and find the mean of this sample is between 95 and 105?

0.9817

Step-by-step explanation:

Given : The Intelligence Quotient (IQ) test scores for adults are normally distributed with

Mean :

Standard deviation :

Sample size : = 50

Let x be the random variable that represents the IQ test scores for adults.

Z-score :

For x =95

For x =105

By using standard normal distribution table , the probability the mean of the sample is between 95 and 105 :-

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

answer: 12

because yes
