A chemistry test has a maximum score of 135 marks. The results achieved by a class of 14 students are listed: 117, 68, 121, 94, 115, 123, 75, 135, 87, 127, 52, 102, 89, 132 Calculate the percentile rank of a mark of 118, to the nearest percentile.

In 2016 the Better Business Bureau settled 84% of complaints they received in the United States. Suppose you have been hired by the Better Business Bureau to investigate the complaints they received this year involving new car dealers. You plan to select a sample of new car dealer complaints to estimate the proportion of complaints the Better Business Bureau is able to settle. Assume the population proportion of complaints settled for new car dealers is 0.84, the same as the overall proportion of complaints settled in 2016. Use the z-table. a. Suppose you select a sample of 200 complaints involving new car dealers. Show the sampling distribution of p. E(p) (to 2 decimals) (to 4 decimals) b. Based upon a sample of 200 complaints, what is the probability that the sample proportion will be within 0.04 of the population proportion (to 4 decimals)? probability : = c. Suppose you select a sample of 460 complaints involving new car dealers. Show the sampling distribution of p. E(F) (to 2…

In some 4.0 grading systems, a student's grade point aversge (GPA) is calculated by assigning letter grades the following numerical values. (See attachment) Use this grading system to find this student's GPA. Round to the nearest hundredth. Tessa's cumulative GPA for 3 semesters was 3.18 for 46 course units. Her fourth semester GPA was 3.72 for 12 course units. What is Tessa's cumulative GPA for all 4 semesters?

 A national forest service wanted to estimate the number of deer in a particular national park. They cotton tag 71 deer and release him back into the park. Later they selected a sample of 272 deer. Of the 272 dear, 17 were tagged, assuming that the portion of tag deer and the sample holds for all deer in the forest, what is the best estimate of the number of deer in the park?
