The biopharm company has developed a stress test for college-aged students. scores on the stress test for such students are approximately normally distributed with a mean of 55 points and a standard deviation of 2 points. scores of 58 points or higher indicate a high level of stress and are of concern to doctors. a random sample of college-aged students will be selected and each will be given this stress test. answer the following questions based on the information given.
(a) what is the probability that the score for the first randomly selected student will be at least 58 points? (show your work)
(b) given that the first randomly selected student has a score of at least 58 points, what is the probability that the next randomly selected student scores below 58 points? (show your work)

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
