ege, Pennsylvania, ranks first with 71.1% of its population made up of coll na random sample of 130 people from State College, more than 50 are no least 4 decimal places and intermediate z-value calculations to 2 decimal

To estimate the mean height of female high school juniors, you take a random sample of 30 female students and get these results (in inches): 72, 51, 67, 68, 61, 69, 58, 56, 60, 56 66, 61, 60, 59, 59, 54, 58, 53, 68, 63 57, 62, 63, 64, 56, 62, 58, 67, 57, 70 If the o is 5.3, based on past research, and you want to construct a 97% confidence interval using (estimate) + (margin of error)= (estimate) + z* what's the margin of error? O A. .968 inches B. 2.1 inches О с. 2.16 D. .968 E.

Can you help me with the code for how to do this in R please?   1. The study "Digital Footprints" ([Pew Internet and American Life Project]("Digital Footprints" (Pew Internet and American Life Project)) reported that 47\% of Internet users have searched for information about themselves online. The 47\% figure was based on a random sample of Internet users. Suppose that the sample size was `n = 400`.     i) Use this information to estimate the true proportion of Internet users who searched information about themselves using a default 95\% confidence interval.        ii) Repeat (i) but instead use a 98\% Confidence Level. Use function `prop.test()`.      iii) What is the main difference between the intervals computed in (i) and (ii)? What do you think is the role of the confidence level in determining the precision of the confidence interval estimate?

After conducting an ANOVA, you end up with the following results:  F(2, 27) = 8.80, p < .05.  How many groups were included in your analysis?   Enter your answer as a whole number with no decimal places (i.e., 10, not 10.01, not 10.1, not 10.001).

Are couples that live together before they get married more likely to end up divorced within five years of marriage compared to couples that live apart before they get married? 217 of the 671 couples from the study who lived together before they got married were divorced within five years of marriage. 132 of the 421 couples from the study who lived apart before they got married were divorced within five years of marriage. What can be concluded at the  = 0.10 level of significance? For this study, we should use        The null and alternative hypotheses would be:                                            The test statistic     =  (please show your answer to 3 decimal places.) The p-value =  (Please show your answer to 4 decimal places.) The p-value is      Based on this, we should      the null hypothesis. Thus, the final conclusion is that ... The results are statistically insignificant at αα = 0.10, so there is statistically significant evidence to conclude that the divorce rate…

Can you help me with the code for this in R please?   2. The article ["CSI Effect Has Juries Wanting More Evidence" (USA Today, 2004)](https://usatoday30.usatoday.com/news/nation/2004-08-05-csi-effect_x.htm) examines how the popularity of crime-scene investigation television shows in influencing jurors' expectation of what evidence should be produced at a trial. In a survey of 500 potential jurors, one study found that 350 were regular watchers of at least one crime-scene forensics television series.       i) Assuming that it is reasonable to regard this sample of 500 potential jurors as representative of potential jurors in the US, use the given information to construct and interpret a 95\% confidence interval for the proportion of all potential jurors who regularly watch at least one crime-scene investigation series.          ii) Using the same sample proportion as part (i), construct a 95\% confidence interval for same proportion but instead use a sample size of 50.           iii)…

Are couples that live together before they get married just as likely to end up divorced within five years of marriage compared to couples that live apart before they get married? 268 of the 674 couples from the study who lived together before they got married were divorced within five years of marriage. 173 of the 405 couples from the study who lived apart before they got married were divorced within five years of marriage.
