Blood donors have been suspected to have an unusual distribution of blood groups. Expected distribution for the blood group donated is 44% of group O, 45% of group A, 8% of group B and 3% of group AB. A random sample of blood group was taken during a blood donation campaign and the results are shown in Table 5. (i) Show evidence that the distribution of the blood group is different from expected at 95% confidence level. (ii) Based on the hypothesis testing in (i), state your conclusion. Blood Group O A B

The production manager in an automobile plant is concerned with the number of cars that do not pass the final quality control inspection. In the last two hours he noted that in a sample of 120 cars only 92 were acceptable. The lower and upper limit of a 95% confidence interval for the true percentage of all cars that would not pass the final quality control inspection would be:
A recent Gallup poll asked a random sample of 1010 Americans to respond to the statement, "If the U.S. fails to develop a more talented workforce, it will fall behind other countries." The 95% confidence interval for the proportion who would respond "Strongly agree" or "Agree" is 0.74 to 0.82. Calculate the point estimate and the margin of error used to create this confidence interval.
According to a report on sleep deprivation by the Centers for Disease Control and Prevention, the proportion of California residents who reported insufficient rest or sleep during each of the preceding 30 days is 8.0%, while this percent is 8.8% for Oregon residents. These data are based on simple random samples of 11,545 California and 4,691 Oregon residents. Suppose we want to calculate a 99% confidence interval for the difference between the proportions of Californians and Oregonians who are sleepdeprived. 1. State the critical value for the interval (3 decimal places): 2. State the difference between the sample proportions, POregon-PCalifornia (3 decimal places): 3. State the standard error of the difference between the proportions (3 decimal places): 4. State the confidence interval being sure to use proper notation (3 decimal places each):

The St. Lucie County Health Department needs to estimate the proportion of all children in the county aged 19-35 months that are completely up to date with all state-recommended immunizations. The St. Lucie County Health Department found that 67% of a random sample of children in the county aged 19-35 months were completely up to date with all state-recommended immunizations. Find three different confidence intervals - one with sample size 239, one with sample size 596, and one with sample size 937. Assume that 67% of the children each sample are completely up to date with all state recommended immunizations. Notice how the sample size affects the margin of error and the width of the interval. Report confidence interval solutions using interval notation. Report all solutions in percent form, rounded to two decimal places, if necessary. When n=239n=239, the margin of error for a 97% confidence interval is given b When n=239n=239, a 97% confidence interval is given by When n=596n=596,…

In a study of the accuracy of fast food drive-through orders, restaurant a had 346 accurate orders and 61 that were not accurate. Construct a 90% confidence interval estimate of the percentage of orders that are not accurate. Compare the results from part A to this 90% confidence interval for the percentage of orders that are not accurate at restaurant B: 0.132< P < 0.189. What do you conclude?
According to a report on sleep deprivation by the Centers for Disease Control and Prevention, the proportion of California residents who reported insufficient rest or sleep during each of the preceding 30 days is 8.0%, while this proportion is 8.8% for Oregon residents. These data are based on simple random samples of 11,545 California and 4,691 Oregon residents. Calculate a 95% confidence interval for the difference between the proportions of Californians and Oregonians who are sleep deprived and interpret it in context of the data. Also, conduct a hypothesis, with alpha = 0.05, test to determine if these data provide strong evidence the rate of sleep deprivation is different for the two states. Construct a 95% confidence interval Which of the following correctly displays the standard error? 0.0046 0.009 0.001 0.00002 0.008
In a random sample of 50 patients undergoing a standard surgical procedure, 15 required medication for post operative pain. In a random sample of 90 patients undergoing a new procedure, only 16 required pain medication. a)Are conditions met to perform inference onthis study? b)Construct and interpret a 95% confidence interval for the difference in the proportions of patients needing pain medication between the old and new procedures. c) A physician claims that the proportion of patients who need pain medication is the same for both procedures. Does the confidence interval contradict this claim? Why/Why not?
Suppose that a safety group surveyed 1,200 drivers. Among those surveyed,78% said that careless or aggressive driving was the biggest threat on the road, and 33% said that cell phone usage by other drivers was the driving behavior that annoyed them the most. Based on these data and assuming that the sample was a simple random sample, construct and interpret a 99% confidence interval estimate for the true proportion in the population of all drivers who are annoyed by cell phone users. The confidence interval estimate is _____ to _____. (Round to three decimal places as needed. Use ascending order.)
In order to estimate the overall proportion of students who favor a shorter semester system, we selected a simple random sample of 36 students and found that 24 of them favor a shorter semester system.(a) Construct a 90% confidence interval for the overall proportion of students who favor a shorter semester system.(b) Find the margin of error associated with this c.i. and interpret the answer in plain language.(c) In order for the margin of error to be no greater than 0.1 (or 10 percentage points), how large a sample should be drawn instead?
