.In the past 30 days, Roger’s Rural Roundup has sold 8, 9, 10, or 11 lottery tickets. It never sold fewer than 8 or more than 11. The owner looked at the past 30 days to determine how many were sold each day. Eight lottery tickets were sold on 10 days, nine lottery tickets were sold on 12 days, ten tickets sold on 6 days, and eleven tickets were sold on 2 days. Develop a probability distribution table from the data (using a relative frequency approach What is the expected value of the distribution? What is the variance of the distribution?

When purchasing bulk orders of batteries, a toy manufacturer uses this acceptance sampling plan. Randomly select and test 45 batteries and determine whether each is within specifications. the entire shipment is accepted if at most 2 batteries do not meet the requirements. A shipment contains 3000 batteries and 2% of them do not meet specifications. What is the probability that this whole shipment will be accepted? Will almost all such shipments be accepted or will many be rejected?

Blue Embrold.. Pointehaven 200 G. PANDOR A study was conducted to determine whether there were significant differences between medical students admitted through special programs (such as retention incentve and guaranteed placement programs) and medical students admitted through the regular admissions criteria. It was found that the graduation rate was 91.9% for the medical students admitted through special programs. A sample of 11 students from the special programs are randomly selected. An event is considered unusual if it has a probability of less than 5%. Round to at least 4 decimal places! a) Compute the probability that at least 10 of them graduated. b) Compute the probability that exactly 8 of them graduated. C) Would it be unusual to randomly select 11 students from the special programs and get exactly 8 that graduate? O no, it is not unusual O yes, it is unusual d) Compute the probability that at most 8 of them graduated. e) Would it be unusual to randomly select 11 students…
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
