A news company reported that 6% of adult Americans have a food allergy. Consider selecting 15 adult Americans at random. Define the random variable x as x = number of people in the sample of 15 that have a food allergy.

Number of people that have food allergy = 1 person (approx.)

Given:

Percentage of American have food allergy = 6 %

Number of people in survey = 15

Find:

Number of people that have food allergy

Computation:

Number of people that have food allergy = Number of people in survey x Percentage

Number of people that have food allergy = 15 x 6 %

Number of people that have food allergy = 0.9

Number of people that have food allergy = 1 person (approx.)

like many students at university, you may be unhappy about the results you attain in exams. you may feel that even with all you are doing there must be something more -- or different-- you could be doing to get better grades. we have all at some time or other heard of that student who only studies a couple of hours for final exams and scores a's every time. we stand in awe of those who seem to breeze through without undue effort and seem to need very little in the way of studying to nail an exam. the reasons for success, in what i think are the vast majority of cases, are less esoteric than many students think: successful students consistently apply a series of productive strategies with view to attaining clearly identified learning and grade goals throughout the academic term.
