The final exam grade of a statistics class has a skewed distribution with mean of 76 and standard deviation of 7.6 neinki sangle of 32 students selected from this class, then what is the probability that average final exam grade of this sample is between 75 and 80? round dedina places)

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

i’m here for points.
