Sea x una variable aleatoria continua que se distribuye normalmente tal que $P(x \leq 27) = 0.50$. 1. La media $\mu$ es 27 2. Si el área bajo la curva normal entre 26 y 28 es 0.4890, entonces la desviación estándar de la distribución es

50. This means that 27 is the median of the distribution. Since the distribution is normal, the median is equal to the mean. Therefore, the mean of the distribution is 27. Show more…

In a sample of 26 individuals, anxiety has been measured, obtaining a mean of 22 and a standard deviation of 10. Based on this data, calculate a confidence interval for the population mean, with a confidence level of 95%.

Si una variable es Normal (μ=10, σ²=1.96) Calcule la probabilidad que X entre 8 y 10. (10 puntos) Calcule la X correspondiente a la percentila del 75%. (10 puntos) Calcule la probabilidad que X sea mayor a 9.5. (10 puntos) Si se toma una muestra de 15 datos, calcule la probabilidad que el promedio este entre 9.2 y 10.1. (10 puntos) Si toma una muestra 10 datos, calcule la probabilidad que el Total este entre 105 y 120. (10 puntos) Calcule la percentila del 90% del Total si la muestra es de 10 datos. (10 puntos)
