The female labor force participation rates (FLFPR) of women in randomly selected countries in 1990 andlatest years of the 1990s are displayed in the table below. Estimate the mean difference between thefemale labor force participation rate in 1990 and the latest years of the 1990s using a 99% confidence level.Round your answers to three decimal places, and use four decimal places for any interim calculations. Youcan use R to get the summary statistics, but you can also solve this problem by hand using skills fromunivariate summaries.Female Labor Force Participation RatesFLFPRCountry25-5419901234567891074.166.168.424.689.427.648.330.235.163.1FLFPR25-54Late 1990s67.863.163.555.884.342.384.235.659.978Hint: Identify the type of t-procedure, and complete the confidence interval accordingly.With 99✓% confidence, it can be said that the mean difference in the female labor forceparticipation rate in 1990 to latest years of the 1990s is between -23.5753 x % and 2.6553 X%.

Which team is the most consistent? Which team, over time, has better average scores? Growing scores? Declining scores? What does the Descriptive Statistics ToolPak tell me about the data? Which team is showing improvement? Can I estimate (or visually predict using the best fit line) which team will have better future performance? If so, which team? How do I know? …and, for whom should I vote?

(same data set) One mean difference is very large, but non-significant and the other is very small, but came out significant. What could be the reason for this outcome? (My difference in means was with 10 participants: -1.1 and with 20 participants: -5.1)

6-4 #17 PLEASE ANSWER ALL QUESTIONS. THANK YOU Transgender Surgery Exercise 6.106 introduces a study investigating the age at which transgender people begin to transition gender and the age at which they have their first experience of gender dysphoria. The study also recorded the age at which they began gender-affirming surgery, and we examine here whether there is a difference in mean age of surgery between trans men and trans women. In the study, the mean age for the 155 trans women in the sample was 41.3 years with a standard deviation of 16.3. The mean age for the 55 trans men in the sample was 35.4 with a standard deviation of 10.8. . Does this sample provide evidence that the mean age of surgery is different between trans women and trans men? (Let Group 1 represent trans women and Group 2 represent trans men.) Find test statistic and p-value. Test statistic = (round to three decimal places)p-value = (round to three decimal places)…
2. (MMC 6.43). The Survey of Study Habits and Attitudes (SSHA) is a psychological test that measures the motivation, attitude toward school, and study habits of students. Each score ranges from 0 to 200. The mean attitude score for U.S. college students is about 110, and the standard deviation is about 25. A teacher who suspects that older students have better attitudes toward school gives the SSHA to 25 students who are at least 30 years of age. Their mean score is = 118.3. a. Assuming that o = 25 for the population of older students, carry out a test of Họ: H = Ha:u > 110 Report the P-value of your test and state your conclusion clearly. = 110 b. What are the required assumptions in part (a)?
