Consider the sampling of 50 electrical components from a production run where, historically, the components average lifetime

Question:

Consider the sampling of 50 electrical components from a production run where, historically, the component’s average lifetime was found to be 950 hours with a standard deviation of 25 hours. The population data is right-skewed and therefore cannot be considered to be normally distributed. Calculate the probability that the sample mean is less than 958 hours.
