Durante las crisis económicas, se despide a obreros y a menudo se les reemplaza con máquinas. Se revisa la historia de 100 trabajadores cuya pérdida del empleo se atribuye a los avances tecnológicos. Por cada uno de esos individuos se determinó si el o ella recibieron un empleo alternativo dentro de la misma compañía, si encontraron un empleo en otra compañía pero trabajando en la misma área, si encontraron trabajo en una nueva área o si llevan desempleados más de un año. Además, se registró el estatus sindical de cada trabajador. La siguiente tabla resume los resultados.

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
