Mean _____ 1. 55 - 145

68% sure the true scores lies in the range of ___________ 2. 100

standard deviation _________ 3. 70 - 130

99% sure the true scores lies in the range of ________ 4. 85 - 115

95 % sure the true scores lies in the range of ________ 5. 15

Solutions

Expert Solution

Solution:

Mean = 100

68% sure the true scores lies in the range of 85 - 115

standard deviation = 15

99% sure the true scores lies in the range of  55 - 145

95 % sure the true scores lies in the range of  70 - 130

Explanation:

Given , Mean = 100 and standard deviation = 15

According to empirical rule ,

68% data lie in the range - and   - .

95% data lie in the range - 2 and   - 2​​​​​​​.

99% data lie in the range - 3 and   - 3​​​​​​​.
