Step-by-step explanation:
Answer:
a) 60 graduates
b) Business and social science.
Step-by-step explanation:
In United States, from 2009 to 2010 the Bachelor's Degrees graduates are made up of 22% for business, 10% for social science, 8% is health related, 6% is education and 54% is others. Given that a sample of 1000 college graduates where used,
a) Number of graduates with education degree is equal to 6% of the total college graduates. Therefore:
Number of graduates with education degree = 6% × 1000 = 0.06 × 1000 = 60 graduates
b) Number of graduates with business degree = 22% × 1000 = 0.22 × 1000 = 220 graduates
Number of graduates with social science degree = 10% × 1000 = 0.1 × 1000 = 100 graduates
Number of graduates with health related degree = 8% × 1000 = 0.08 × 1000 = 80 graduates
Number of graduates with other degree = 54% × 1000 = 0.54 × 1000 = 540 graduates
Since Many graduates earn degrees in fields that result in high-paying jobs, the two fields most likely pay more than the others are that of business and social science.
The score of 96 is 2 standard deviations above the mean score. Using the empirical rule for a normal distribution, the probability of a score above 96 is 0.0235.
Therefore the number of students scoring above 96 is given by:
