    to 36 students to see if the attitudes of students toward the mentally ill would change. The results of the class of 36 that watched the film had a score of 70. The results of the class that did not watch the film had a score of 75. The standard deviation is 12. When the alpha is set to 0.05. .05 is a mid-probability. It means we’re using to reduce the likelihood of errors. It means there is a 5% chance that an error may occur. These errors usually will lead to the rejection of the null hypothesis

    We then recorded those values. 3.We found the mass of a standard mass on the balance pan. We recorded the mass as accurately as was allowed by the balance. 4.We moved the smallest counterweight over slightly until there was the slightest deviation from the zero point. We recorded that value. Then‚ we moved the counterweight in the opposite direction. We recorded that value. 5.We measured and recorded the mass of each of the two objects of unknown mass. We added those values to the class
