Given that z20 = –2 and z50= – 1, which of the following do you know? 1.) the variance is 10. 2.) the standard deviation is 30. 3.) the mean is 80. 4.) the median is 40. 5.) the data point x=20 is 2 standard deviations form the mean 6.) the data point x=50 is 1 standard deviation from the mean 7.) the data point x=45 has a z-valued of 1.5

it is 2;3;5;6

Step-by-step explanation:

Given that z20 = –2 and z 50= –1, which of the following do you know?

The variance is 10.

The standard deviation is 30.

The mean is 80.

The median is 40.

The data point x = 20 is 2 standard deviations from the mean.

The data point x = 50 is 1 standard deviation from the mean.

The data point x = 45 has a z-value of 1.5.
