When dragons on planet Pern lay eggs, the eggs are either green or yellow. The biologists have observed over the years that 18% of the eggs are yellow, and the rest green. Next spring the lead scientist has permission to randomly select 41 of the dragon eggs to incubate. Consider all the possible samples of 41 dragon eggs.What is the mean number of yellow eggs in samples of 41 eggs? (that is the same as asking for the expected value of the number of yellow eggs)(Give answer correct to at least one decimal place.)mean = What is the standard deviation in the number of yellow eggs in samples of size 41?(Give answer correct to at least one decimal place.)standard deviation = What is the variance in the number of yellow eggs in samples of size 41?(Remember to calculate the answer using at least 5 decimal places, then give answer correct to at least one decimal place.)variance =
Samples of pages were randomly selected from three different novels. The Flesch Reading Ease scores were obtained from each page, and the TI-83/84 Plus calculator results from analysis of variance are given below. Use a 0.05 significance level to test the claim that the three books have the same mean Flesch Reading Ease score. iClick the icon to view the TI-83/84 Plus calculator results. What is the conclusion for this hypothesis test? C O A. Reject Ho. There is sufficient evidence to warrant rejection of the claim that the three books have the same mean Flesch Reading Ease score.

A paper reported that in a representative sample of 282 American teens age 16 to 17, there were 78 who indicated that they had sent a text message while driving. For purposes of this exercise, assume that this sample is a random sample of 16- to 17-year-old Americans. Do these data provide convincing evidence that more than a quarter of Americans age 16 to 17 have sent a text message while driving? Test the appropriate hypotheses using a significance level of 0.01. (Round your test statistic to two decimal places and your P-value to four decimal places.) Z = P-value %3D State your conclusion. Reject Ho. We have convincing evidence that more than a quarter of Americans age 16 to 17 have sent a text message while driving. Do not reject Ho.

In a study of 809 randomly selected medical malpractice lawsuits, it was found that 509 of them were dropped or dismissed. Use a 0.01 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed. Identify the null and alternative hypotheses. The null hypothesis, Ho, is a statement that the value of a population parameter (such as proportion, p, mean, µ, or standard deviation, o) is equal to some claimed value. The alternative hypothesis, H,, is the statement that the parameter has a value that somehow differs from the null hypothesis and uses the inequalities , or #, corresponding to a left, right, or two-tailed test, respectively. 5
The proportion P residence in a community recycles traditionally been 70%. Policymaker claims of the unfortunate less than 70% now that one of the recycling centers has been relocated. It's 137 out of a random sample of 205 residence in the community said they recycle, is there enough evidence to support the policy makers claim at the 0.05 level of significance?
