Directions: Find the mean and standard deviation of the sampling distribution of sample means using the given information.   (Note: tilde sign (~) means approximately)

1. µ = 35 and σ = 9; n = 64

1. µx = 35 and σx = ~1.1
2. µx = 53 and σx = ~1.9
3. µx = 8 and σx = ~64

D. None of the above

2. µ = 28 and σ = 6; n = 81

1. µx= 10 and σx = ~0.7
2. µx= 14 and σx = ~0.9
3. µx= 28 and σx = ~0.7
4. None of the above

3. µ = 12 and σ = 2.3; n = 36

1. µx= 13 and σx = ~0.78
2. µx= 12 and σx = ~0.85
3. µx= 21 and σx = ~0.90
4. µx= 12 and σx = ~0.38

4. µ = 9.5 and σ = 10; n = 39

1. µx = 10.5 and σx = ~1.40
2. µx = 5.9 and σx = ~1.00
3. µx = 6.5 and σx = ~1.40
4. µx = 9.5 and σx = ~1.60

5. A study of the latest diet fad claimed the amount of weight lost by all people on this diet varied by a standard deviation of 5.8 pounds. If a sampling distribution is created using samples of size 100, what would be the standard deviation of the sampling distribution of the sampling means?

1. σx = ~0.58
2. σx = ~0.02
3. σx = ~0.89
4. σx = ~0.23
