Pochacco hypothesizes that giraffes will look longer at human infants than at human adults. In his zoo, he has 10 giraffes. They were all shown 2 pictures of humans (one infant and one adult) for 30 seconds, individually (each giraffe is shown both pictures). What statistical test might be appropriate for this study?

this is part 2 of a question. Although older Americans are most afraid of crime, it is young people who are more likely to be the actual victims of crime. It seems that older people are more cautious about the people with whom they associate. A national survey showed that 10% of all people ages 16-19 have been victims of crime.† At a high school, a random sample of n = 66 students (ages 16-19) showed that r = 11 had been victims of a crime. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value a small amount and thereby produce a slightly more "conservative" answer.   Find a 90% confidence interval for the proportion of students in this school (ages 16-19) who have been victims of a crime. (Round your answer to three decimal places.) lower limit       upper limit       (c) How large a sample size should be used to be 95% sure that the sample proportion p̂ is within…

Dorinda is in second grade. She asks 6 of her classmates if they like to wear friendship bracelets. Four of her classmates said yes. Based on her findings, would it be reasonable to assume that about 2/3 of the pupils at her school (which has kindergarten through fifth grade) would also like to wear friendship bracelets? Why or why not?
