where Iwage is the natural logarithm of hourly wage in US$, educ is years of education, exper is years of work
experience and exper2 is experience squared (exper * exper).
What is the exact effect in percent of a 15 years increase in education on predicted wage?
State your answer in percentages. For example, if you think the answer is 10% write 10 instead of 0.1. Do not use the %
symbol.
QUESTION 45
Consider the following scenario:
• The significance level is 5%
• Of all tested hypotheses, 10% are true
• The statistical power is 60%
What is the probability of the finding being true, given that the estimate is statistically significant?
(State your answer as percentage without the percent symbol. For example, if you think the correct answer is 10%, just
state 10)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0d63c4c0-1d60-4fb3-84fd-f3eaa9e9798b%2F7bc344bc-d1ce-4cfa-a34c-442568b52872%2Fe25aaou_processed.jpeg&w=3840&q=75)
