Researchers surveyed 100 students on which superpower they would most like
to have. This two-way table displays data for the sample of students who
responded to the survey:
Superpower Male Female TOTAL
Fly
26 12 38
Invisibility 12 32 44
Other 10 8 18
TOTAL 48 52 100
A student will be chosen at random.
PROBLEM 1
Find the probability that the student chose to fly as their superpower.
P (fly) =

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120 lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 125 lb and a standard deviation of 28.1 lb. a)if a pilot is randomly selected, find the probability that his weight is between 120 lb and 161 lb.the probability is approximately? b. if 36 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 161 lb. the probability is approximately? c. when redesigning the ejection seat, which probability is more relevant? . part (b) because the seat performance for a single pilot is more important. b. part (b) because the seat performance for a sample of pilots is more important. c. part (a) because the seat performance for a sample of pilots is more important. d. part (a) because the seat performance for a single pilot is more important.
