If there is an overall 120 movies, the mean is 109.408 And the standard deviation is 19.606. One of the variables Average around 126, how many standard deviation is that average below or above the mean? What is the probability that the main runtime of a random sample of 10 movies are at least as long as 126 for runtime, what would the sketch look like and round it to the third decimal place. If that was based on a histogram and the underlying population distribution is not nearly normal, if it was to be assumed that the population mean And standard deviation equal the same mean and standard deviation, what would change?
