A population has a mean of u = 50 and a standard deviation of a = 10. If 3 points were added to every score in the population, what would be the new values for the mean and standard deviation? O The new mean is u = 47, and the new standard deviation is a = 13. The new mean is u = 47, and the standard deviation is still a = 10. O The new mean is u = 53, and the standard deviation is still a = 10. The mean is still u = 50, and the new standard deviation is a = 13. If every score in the population were multiplied by 2, what would be the new values for the mean and standard deviation? O The new mean is u = 100, and the new standard deviation is still a = 10. O The new mean is u = 52, and the new standard deviation is o = 20. O The new mean is u = 100, and the new standard deviation is a = 20. The mean is still u = 50, and the new standard deviation is o = 20.

Question
A population has a mean of u = 50 and a standard deviation of a = 10.
If 3 points were added to every score in the population, what would be the new values for the mean and standard deviation?
O The new mean is u = 47, and the new standard deviation is a = 13.
The new mean is u = 47, and the standard deviation is still a = 10.
O The new mean is u = 53, and the standard deviation is still o = 10.
O The mean is still u = 50, and the new standard deviation is a = 13.
If every score in the population were multiplied by 2, what would be the new values for the mean and standard deviation?
The new mean is µ = 100, and the new standard deviation is still a = 10.
The new mean is u = 52, and the new standard deviation is o = 20.
The new mean is u = 100, and the new standard deviation is a = 20.
The mean is still u = 50, and the new standard deviation is o = 20.
