Please help by explaining the concepts underlying how the following problem is solved

The distribution of bladder volumes in men is approximately Normal with mean 550 milliliters (ml) and standard deviation 100 ml. In women, bladder volumes are approximately Normal with mean 400 ml and standard deviation 75 ml. Use the technology of your choice to answer the questions. (a) How large are the largest 10% of bladder volumes among men? (Enter your answer rounded to two decimal places.) 0 Largest 10%: 2 678 ml. (b) How large are the largest 5% on bladder volumes among women? (Enter your answer rounded to two decimal places.) Largest 5%: 2 523 ml. (c) Obtain and compare the first quartile of bladder volumes for the population of adult men and for the population of adult women. Select the correct comparison statement. O The first quartile for size of mens' bladders is about 569 ml as compared to the first quartile for women at about 286 ml. O The first quartile for size of mens' bladders is about 349 ml as compared to the first quartile for women at about 483 ml. O The first quartile for size of mens' bladders is about 483 ml as compared to the first quartile for women at about 230 ml. O The first quartile for size of mens' bladders is about 483 ml as compared to the first quartile for women at about 349 ml
