Question

Your statistics instructor claims that 60% of the students who take her Elements of Statistics and Data Analysis class go through life feeling more enriched. For some reason, most people do not believe her. You decide to check this out on your own. You randomly sample 64 of her past statistics students and find that 34 feel more enriched as a result of her class. What can you infer from the results of your study?

Answer 1

Her claims are wrong as per my studied

Explanation:

She says that 60% of the students are more enriched.

total number of students = 64

if 34 people feel more enriched, the ratio of the students that feel enriched to the total number of students then is ? \frac{34}{64} = 0.53125.

converting .53125 to percentage we'd multiply by 100%.

and hence have .53125*100% =53.125%

since 53.125% is less that the 60% claimed by the instructor, then i infer that her claims are wrong
