In 2015 the proportion of all college medical students who planned to enter the same medical specialty as their father was 0.25. A new 2019 survey of a random sample of 500 medical college students showed that 100 planned to enter their fathers’ specialty. Using α = 0.05, does this data indicate that the proportion of all medical college students who planned to enter the same medical specialty as their father has decreased? 5) What is the appropriate distribution for performing the analysis? a Uniform b Binomial c z distribution d t distribution e Chi Square 6) What is the Pvalue?   7) What is the Hypothesis Test Decision? a Do not Reject the Null Hypothesis b Reject the Null Hypothesis c Insufficient information
