Question 4
This question requires evidence of a procedure to obtain all the points.

A researcher wants to estimate the average age of newly diagnosed patients with type II diabetes mellitus in a certain population of adults. From a sample of 10 subjects, the mean age at diagnosis was 45.8 years and the standard deviation in the sample was 12.5 years. If the population from which the sample was drawn follows a normal distribution. It is desired to prove that the average age of diagnosis of these patients is different from 50 years through a confidence interval, with a 5% significance. What would be the most appropriate interval estimate for this analysis?

Un investigador quiere estimar el promedio de edad de los pacientes recién diagnosticados con diabetes mellitus tipo II en cierta población de adultos. De una muestra de 10 sujetos, el promedio de edad al momento del diagnóstico era de 45.8 años y la desviación estándar en la muestra fue de 12.5 años. Si la población de donde se extrajo la muestra sigue una distribución normal. Se desea probar que el promedio de edad de diagnostico de estos pacientes es diferente de 50 años a traves de un intervalo de confianza, con un 5% de significancia. Cuál seria la estimacion de intervalo mas adecuada para este análisis?
