Given a gamma distribution with alpha equal to 3 and ß unknown. Find the

Listed below are pulse rates​ (beats per​ minute) from samples of adult males and females. Does there appear to be a​difference? Find the coefficient of variation for each of the two​ samples; then compare the variation. A. The coefficient of variation for the male pulse rates iS ​(Type an integer or decimal rounded to one decimal place as​ needed.)   B. The coefficient of variation for the female pulse rates is ​(Type an integer or decimal rounded to one decimal place as​ needed.)

Find the z-score corresponding to the given value and use the z-score to determine whether the value is significantly low or high.  Consider a score to be significantly low if its z-score is less than  or equal to -2.  Consider a z-score to be significantly high if it is greater than or equal to 2.  Round the z-score to the nearest tenth if necessary. A body temperature of 96.7° F given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°.
