When dragons on planet Dathomir lay eggs, the eggs are either green or yellow. The biologists have observed over the years that 19% of the eggs are yellow, and the rest green. Next spring, the lead scientist has permission to randomly select 57 of the dragon eggs to incubate. Consider all the possible samples of 57 dragon eggs. What is the mean (μ) number of yellow eggs in samples of 57 eggs?(Please show your answer to 1 decimal place) What is the standard deviation (σ) in the number of yellow eggs in samples of size 57? (Please show your answer to 1 decimal place)

The Census Bureau of the U.S. government found that 13% of adults did not finish high school, 30% graduated from high school only, 29% had some college education but did not obtain a bachelor’s degree, and 28% were college graduates. To see if these proportions were consistent with those people who lived in the Lincoln County area, a local researcher selected a random sample of 300 adults and found that 43 did not finish high school, 76 were high school graduates only, 96 had some college education, and 85 were college graduates. At α = 0.10, test the claim that the proportions are the same for the adults in Lincoln County as those stated by the Census Bureau.
Students in an elementary school both boys and girls were asked if they are willing to write a letter to their mother on Mother's Day as an assignment. Out of the 30 boys, only 9 answered "yes" while out of the 45 girls, 39 said that they are willing to write to their mother on Mother's Day. At 99% level of confidence, is there enough evidence to say that the proportion who said "yes" is more for girls than boys? .

The U.S. Department of Transportation, National Highway Traffic Safety Administration, reported that 77% of all fatally injured automobile drivers were intoxicated. A random sample of 53 records of automobile driver fatalities in a certain county showed that 33 involved an intoxicated driver. Do these data indicate that the population proportion of driver fatalities related to alcohol is less than 77% in Kit Carson County? Use a = 0.01. (a) What is the level of significance? State the null and alternate hypotheses. O Ho: p = 0.77; H1: p = 0.77 O Ho: p 0.77 O Ho: p = 0.77; H1: p 5 and ng > 5. O The standard normal, since np > 5 and ng > 5. The Student's t, since np < 5 and nq < 5. O The standard normal, since np < 5 and ng < 5. What is the value of the sample test statistic? (Round your answer to two decimal places.) (c) Find the P-value of the test statistic. (Round your answer to four decimal places.)
Suzette does an experiment where she collects date from 5 women snd obtains the scores: 4, 4, 5, 2, 5. She hypothesizes that the population mean for the population from which these scores are drawn is 3. She wants to test whether this hypothesis is true. What is the alternative hypothesis she is testing?
A reporter writing for a national newspaper claimed that representatives of school districts were falsely reporting their students’ performance on standardized tests. Over 90% of the nation’s school districts report that their students are performing above the national average, and the reporter claimed that isn’t possible. It is possible. a) Provide a list of 10 numbers for which 90% are above the mean. b) What can you infer about the nation’s school districts if 90% of them really are performing above the national average?
John wants to open a learning center for high school students in his community. John wants to compare the average time area high school students spend studying per week with the regional average, 20.5 hours. John surveys 25 randomly selected local high school students, asking how much time they spend studying in a typical week. Graphs of his sample data show no strong skewness or outliers. Choose the correct inference procedure that John should use to test if the mean weekly study time from his sample differs from 20.5 hours: one-sample, two-sided z-test for a proportion one-sample, right-tailed t-test for a mean one-sample, left-tailed t-test for a mean one-sample, two-sided t-test for a mean

3 A researcher wants to determine the mean income of adults in a particular state. She decides to take a random sample of 1525 citizens with a driver's license from the registry maintained by the Department of Motor Vehicles in that state, and record their incomes. Which one of the following statements is NOT correct? * The sample would be biased since some people without a license may be too poor to own a car and others may choose to use public transportation The sample would not be representative of adults, since teenagers would be included in the sample. Taking a bigger sample from the registry would solve any problems with possible bias People who had recently moved from another state may not yet be included in the DMV registry.
