Note that, sampling distribution of sample mean denotes the probability distribution of the sample mean. Now,
18) the value of sample mean, 35 lies in left tail of the distribution.. this suggests that, the value is unusual but might occur occasionally.
19) Also, the value of 149 is extreme observation in right tail of the distribution, we can infer that - the value is unusual but might occur occasionally.
Add Answer to:
the picture above for reference, need help with #18 and #19
please in the second picture!...

#3 One of the most common ways of measuring intelligence is the IQ test. IQ scores in the US population have an average of µ = 100 and a standard deviation of σ = 15. Suppose a researcher wanted to test whether socioeconomic status (SES) has an effect on IQ scores. The researcher takes a random sample of n = 100 people, selected from a list of the 1000 richest people in the United States. a. Based on this information,...
