Question 11 of 34 Each of the following are characteristics of the sampling distribution of the mean except .a. The sampling distribution 12. 13. of the mean has the same mean as the original population. 14. 15 16. 17 18. 19 20. 21. 22. 23. 24. 25. 26. 27 28. 29 b. If the original population is normally distributed, the sampling distribution of the mean will also be normal. C. The standard deviation of the sampling distribution of the mean is referred to as the standard error. O d. If the original population is not normally distributed, the sampling distribution of the mean will also be approximately normal for large sample sizes. e. All of these choices are characteristics of the sampling distribution of the mean.

Explanation / Answer

Solution:-

11. option e. All of these choices are characteristcs of the sampling distribution of the mean.

17) option d. 0.0202
Explanation:

t(1.3) = (1.3-1.4)/0.0487 = -2.0548
P(x-bar < 1.3) = P(t < -2.0548 when df = 151)
= tcdf(-100,-2.0548,151)
= 0.0208

20. option a. True.

22. option c. 1.50

Explanation : 15/sqrt(100) = 1.5

23. optin b. 3.125
  
=> 25/sqrt(64) = 3.125

27. option a. True
