Question

Q8 and Q9: The following normal distribution curve is constructed based on numerous "sample mean vu cach of which having the sample size of 36. As can be seen, the population mean is 10 an values are located anywhere between 4 and 16. d most sample mean 8. Estimate the approximate "standard error" of the sample mean distribution? Be mindful about the definition of the standard error. Show your solution on the blank space to receive full credits. B) 1.5 C) 2 D) 3 E) 4 eol 2 eel 9. What should be the population standard deviation be careful not standard error)? Show your - A) 1 solution on the blank space below to receive full credits. B) 1.5 C) 2 D) 12 E) 14

Explanation / Answer

The sample mean = 10

X = 16

z value for the mean = 0.5

=> Population standard deviation = (X - ) / z

= (16 - 10) / 0.5

= 12

Sample standard deviation s = / n = 12 / 36 = 12 / 6 = 2.

Thus the answer is

8. C) 2

9. D) 12.
