Teen obesity: the 2013 national youth risk behavior survey (yrbs) reported that 13.7% of u. s. students in grades 9 through 12 who attend public and private school were obese. after seeing extensive efforts to educate parents and teens on healthy lifestyles, we want to know if the proportion has decreased this year. we select a random sample of 200 u. s. students and find that 11% are obese. after performing the hypothesis test for p = 0.137 versus p < 0.137, we obtain a p‑value of 0.133. which of the following interpretations of the p‑value is correct? there is a 13.3% chance that 13.7% of u. s. students in grades 9 through 12 who attend public and private school were obese this year. there is a 13.3% chance that a sample of 200 u. s. students in grades 9 through 12 who attend public and private school will have 11% or fewer obese students if 13.7% of the population is obese this year. there is a 13.3% chance that 11% of u. s. students in grades 9 through 12 who attend public and private school were obese this year. there is a 13.3% chance that 11% of u. s. students in grades 9 through 12 who attend public and private school were obese this year if 13.7% were obese in 2013.

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:  

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
