# Raw Score

Details: 1. What is the between a raw score of 113 and 126 in a normal distribution with a mean of 100 and a standard deviation of 10? Find the area below and under the score of 135.

2. Test null hypothesis that urban and rural residents both have the same attitude toward gun control(data1). Group 1 is a group of the urban residents; group 2 is a group of the rural residents. set type I error rate at .05.
