Paragraph Styles 4. Reading is fundamental to a teenager's ability to perform well in school. Assume a researcher is interested in the ability of the number of books read over the summer to predict ACT Reading scores. Using a random sample of 10 random high school students the researchers recorded the number of books read over the summer and the students' ACT Reading scores.

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)…
