Answer #1

We make a fundamental assumption that her performences in Algebra and Physics are alike.


Average of algebra is 80.6
Average of Physics is 85.6

Student scores 75 in algebra which is below the mean.

There are 3 enteries below the mean for algebra: 75,75 and 71
Student is below average but now the worst performer.

There are 3 enteries below the mean for physics: 82,82 and 80
Since student is below average or below the mean, but not the worst performer, it is safe to predict her physics final score to be 82.

Students completed a high school senior level standardized algebra exam. Major for students was also recorded. Data in terms of percent correct is recorded below for 32 students. We are interested to see if there is any difference between students' high-school algebra test scores and subsequent declared college major. These students have now also just completed the same college-level calculus class and received a grade. We are therefore now also interested to see if there is any relationship between the...

In a certain school district, it was observed that 31% of the students in the element schools were classified as only children (no siblings). However, in the special program for talented and gifted children, 77 out of 204 students are only children. The school district administrators want to know if the proportion of only children in the special program is significantly different from the proportion for the school district. Test at the α=0.05α=0.05 level of significance. Using the normal approximation...
