According to a survey, the distribution of graduate science students in doctorate-granting institutions is shown to the right. Frequencies are in thousands. A graduate science student who Field is attending a doctorate-granting institution is selected at random. Complete parts a through c. Frequency - Physical sciences 34.7 Environmental sciences 11.1 Mathematical sciences 17.5 Computer sciences Agricultural sciences Biological sciences Psychology 43.6 11.8 64.5 45.1 Social sciences 88.5 a. Determine the probability that the field of the student obtained is psychology. (Round to three decimal places as needed.)

Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 102 people in the 18-21 age bracket and finds that 87 of them respond and 15 refuse to respond. When 249 people in the 22-29 age bracket are contacted, 220 respond and 29 refuse to respond. Assume that 1 of the 351 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who responds. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. P(22-29 or responds) = %3D (Hint: It might be helpful to organize the data into a table first.) Submit Question 17,194 7. NOV tv 17 MacBook Air
