Read the following paragraph and answer the five questions, which follow:

An environmental psychologist hypothesized that the noise would adversely affect the performance on mental tasks. One hundred and fifty subjects, 75 boys and 75 girls, studying in the twelfth standard, in the age range of 17 to 19 years and in the IQ range of 85 to 115, constituted the initial pool of subjects. Three group of equal size were formed by random assignment. Group I performed under high noise condition (75 decibels), Group II performed under moderate noise condition (60 decibels), and Group III performed under silent condition. Each subject was instructed to solve 45 simple numerical problems in the allotted time of 90 minutes. The mean number of correctly solve problems were twenty-four, twenty and fifteen respectively. The intergroup mean reference were statistically significant. (June)
