he starting time of a class is uniformly distributed between 10:00 and 10:05. If a student arrives early and has to wait t minutes for the class to start, then the student incurs a penalty of At, which accounts for the waste in the student's time. On the other hand, if the student arrives t minutes after the class has started, then the student incurs a penalty of A2t, which accounts for the information the student has missed. If the student arrives at x minutes after 10:00, what is the expected penalty incurred by the student? What value of x minimizes the expected penalty?

The university administrator wants a quick estimate of the average course size, i.e. how many students are enrolled in one course on average. However, since he does not want the faculty to find out about his interest, he has decided to use the students as his help. He has decided to randomly select 100 students to find out and report to him the number or numbers of students in his course or courses. Thus, his estimate of the average course size is the average of the numbers reported by the students.(a) Does such a procedure serve his purpose?(b) If you answered yes to the previous question, explain why. If you answered no to the previous question, present a more efficient way.
A survey found that in a sample of 100 families, 37 owned cats. A survey done 5 years ago found that in a sample of 80 families, 34 owned cats. At ? = 0.05 has the proportion of cat owners changed over the 5-year period?
A student received an A- in Engineering Math (3 credits), a B+ in introduction to PDT ( 3 credits), an B in Client server ( 3 credits), and a A in Technical writing ( 2 credits). Assuming that, A = 4 grade points, A- = 3.7 grade points, B+ = 3.3 grade points, B = 3 grade %3D %3D points, B- = 2.7 grade points, and C+ = 2.3 grade point, C = 2 %3D grade points and C- = 1.7 grade points. Find the student's grade point average (GPA)? [2 decimal place calculation] O a. 7.37 b. 3.37 О с. 3.73 d. None of the option is correct
One of the characteristics of the workday for cargo vehicle drivers is that if the driving period is less than 5 hours, the driver is entitled to a 24-minute rest break. If a driver has a driving period of 3 hours and 30 minutes, what percentage of the driving period does the rest period represent?
Please clearly shows the steps. I'm not sure if my answer(1/3) is correct, so please just ignore it and calculate by yourself.
A media personality argues that global temperatures are not rising, because every year an increase is reported, such as 0.09 degrees C. The difference from the previous year is less than the margin of error of about 0.13 degrees C, so that difference should be ignored. What is a strong counter argument? The difference is only 0.4 but that is still a significant change. The change of 0.9 is not a lot and thus should be ignored. The margin of error is larger than the increase so we should consider it an issue just extra information and thus can be ignored. The margin of error is quite small compared to the change year over year, so it is a significant issue.
AJ’s sleep pattern had been fluctuating due to stress and diet, so he started to keep a diary of how many hours he slept each night. On the 4th night after he started the diary, AJ slept 9.4 hours, which was the most sleep he got any night. Gradually, he got less sleep each successive night until, on the 18th night after he started the diary, AJ slept 6.2 hours, which was the least sleep he got any night. After keeping his diary for 6 months, he realized that the number of hours he got each night followed a sinusoidal curve. Let t be the number of nights since he started his diary, and s be how many hours he slept that night. It may be helpful to draw a crude sketch of the sleep time function and label the known t − and s − values on it. POSITIVE or NEGATIVE SIN or COS Maximum s − value = Minimum s − value = ______________ ______________ Middle s − value = ______________ = D Amplitude = ______________ = A ⇒ B = ______________ Given the crude sketch of the height function, the…
A student pursuing a degree in English as a second language believes the proportion female factory workers who can't speak English is less than the proportion of male factory workers who can't speak English. To test her claim she randomly selects 373 female factory workers and out of them 43 could not speak English. She then randomly selects 215 male factory workers and out of them 65 could not speak English. Test her claim at .=0.05 to see if she was right. The correct hypotheses are: H : PF Pu (claim) H : PF 2 PM HA: PF < Pr (claim) H : PF = PM HA: PF + PM (claim) Since the level of signficance s0.05 the critical value is-1.64s The test statistic is pound to 3 places) The pvalue is round to 3 places) The decision can be made to oreject H, odo not reject í, The final conclusion is that: There is enough evidence to reject the claim that the proportion female factory workers who can't speak English is less than the proportion of male factory workers who can't speak English. There is…
Our family brought lots of hot dogs along on our latest camping trip. However, after setting up the tent, we didn’t take care to make sure that the food was safe – and raccoons ate 1/4 of the hot dogs! Grumbling, we cleaned up the mess, then ate 12 hot dogs for lunch. But we forgot to put the rest away when we went hiking, and lost 1/6 of our dwindling supply to jays! Just as a precaution, Mom went to the store and bought enough hot dogs to increase our supply by 2/5. Our campsite neighbors, however, ran out of food, so we gave them 3/7 of our remaining hot dogs and then ate 12 hot dogs for our dinner. That night, bears got 3/4 of the last part of our supply, and in the morning there were only 3 hot dogs left! How many hot dogs did we start with? (Next time maybe we should just bring granola bars...)
