A lecture hall has 200 seats with folding arm tablets, 26 of which are designed for left-handers. The typical size of classes that meet there is 186 , and we can assume that about 15 % of students are left-handed. Use a Normal approximation to find the probability that a right-handed student in one of these classes is forced to use a lefty arm tablet.
The probability is %.
Here it is given that probability of left hand is 0.15, so probability of right handed is 0.85
So
Standard deviation is
Now we need to find

A lecture hall has 190 seats with folding arm tablets, 29 of which are designed for left-handers. The average size of classes that meet there is 183, and we can assume that about 14% of students are left-handed.

A city ballot includes a local initiative that would legalize gambling. The issue is hotly contested, and two groups decide to conduct polls to predict the outcome. The local newspaper finds that 53% of 1600 randomly selected voters plan to vote "yes," while a college Statistics class finds 54% of 350 randomly selected voters in support. Both groups will create 95% confidence intervals. Assume that all voters know how they intend to vote and that the initiative requires a majority...
Two professors at a local college developed a new teaching curriculum designed to increase students' grades in math classes. In a typical developmental math course, 4949% of the students complete the course with a letter grade of A, B, or C. In the experimental course, of the 1919 students enrolled, 1212 completed the course with a letter grade of A, B, or C. Is the experimental course effective at the alpha equals 0.05α=0.05 level of significance? Complete parts (a) through...
