Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 185 eligible voters aged 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged 18-24, 22% of them voted. Probability that fewer than 44 voted

A financial firm is performing an assessment test and relies on a random sampling of their accounts. Suppose this firm has 60026002 customer accounts numbered from 00010001 to 60026002. One account is to be chosen at random. What is the probability that the selected account number is 29402940? answer:

A survey of property owners' opinions about a street-widening project was taken to determine if owners' opinions were related to the distance between their home and the street. A randomly selected sample of 100 property owners was contacted and the results are shown next.     Opinion  Front Footage For Undecided Against  Under 45 feet 12 4 4  45-120 feet 35 5 30  Over 120 feet 3 2 5 What is the expected frequency for people against the project and who have over 120 feet of property foot-frontage?   Select one: a. 1.1 b. 3.9 c. 5.0 d. 5.5

When studying radioactive​ material, a nuclear engineer found that over 365​ days, 1,000,000 radioactive atoms decayed to 979,748 radioactive​ atoms, so 20,252 atoms decayed during 365 days.   a. Find the mean number of radioactive atoms that decayed in a day. b. Find the probability that on a given​ day, 52 radioactive atoms decayed.

Probability = B. 7 or more accidents occur in a week. Probability = C. One accident occurs today. Probability =

Assume that when human resource managers are randomly​ selected, 38% say job applicants should follow up within two weeks. If 30 human resource managers are randomly​ selected, find the probability that exactly 23 of them say job applicants should follow up within two weeks. a.The probability is?

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
