45 . For a data set of the pulse rates for a sample of adult females , the lowest pulse rate is 38 beats per minute , the mean of the listed pulse rates is * = 75 . 0 beats per minute , and their standard deviation is s = 14 . 2 beats per minute . 2 . What is the difference between the pulse rate of 38 beats per minute and the mean pulse rate of the females ?" b . How many standard deviations is that [ the difference found in part ( a ) ] ?" C. Convert the pulse rate of 38 beats per minutes to a Z score . d . If we consider data speeds that convert to z scores between - 2 and 2 to be neither significantly low nor significantly high , is the pulse rate of 38 beats per minute significant ? a . The difference is beats per minute . ( Type an integer or a decimal . Do not round . ) b . The difference is standard deviations . ( Round to two decimal places as needed . ) C . The z score is Z = ( Round to two decimal places as needed . ) d . The lowest pulse rate is ( 1 ) ( 1 ) O not significant . O significantly high . O significantly low
