The heights of adult men in america are normally distributed, with a mean of 69.3 inches and a standard deviation of 2.68 inches. the heights of adult women in america are also normally distributed, but with a mean of 64.8 inches and a standard deviation of 2.52 inches. a) if a man is 6 feet 3 inches tall, what is his z-score (to two decimal places)? z = ) what percentage of men are shorter than 6 feet 3 inches? round to nearest tenth of a %c) if a woman is 5 feet 11 inches tall, what is her z-score (to two decimal places)? z =) who is relatively taller: a 6'3" american man or a 5'11" american woman? defend your choice in a meaningful sentence.

a) z-score for men is 2.13. b) percentage of men shorter than 6 feet 3 inches is 98%. c) z-score for women is 2.46. d) The American woman is relatively taller.

Step-by-step explanation:

The z-score is calculate by the difference between the value and the mean divided by the standard deviation.  For men, z-score will be 2.13 and for women it will be 2.46. If you reference to the distribution graph, a z-score of about 2 is approximately 98% of cumulative percentage. This means that 98% of men is shorter than 6 feet 3 inches tall. The American woman of 5'11" is relatively taller than a men of 6'3" because of its z-score. Since it is closer to 3, the percentage of women shorter than 5'11" will be over 98% and lower than 99%, which is already taller than the value found for men of 6'3".  

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
