A botanist wants to determine if a fertilizer is effective in Which of the following is a valid conclusion? the growth of plants. He randomly selects 100 of the same type of seedling and randomly assigns them to two groups: one that uses the fertilizer, and one that does not. He makes sure the plants all have the same amount of water, soil, and light for two months. At the end of two months, he measures the heights of the plants and finds that the ones receiving the fertilizer are significantly taller. Inferences can be made for all plants, and the conclusion can be drawn that the fertilizer will help al plants grow taller. Inferences cannot be made for all plants, and the conclusion cannot be drawn that the fertilizer will help these plants grow taller. Inferences can be made for these types of plants, and the conclusion can be drawn that the fertilizer will help these types of plants grow taller. 29 O Inferences cannot be made for these types of plants, and the conclusion cannot be drawn that the fertilizer will help these types of plants grow taller.

Professor Fair believes that extra time does not improve grades on exams. He randomly divided a group of 300 students into two groups and gave them all the same test. One group had exactly 1 hour in which to finish the test, and the other group could stay as long as desired. The results are shown in the following table. Test at the 0.01 level of significance that time to complete a test and test results are independent.

70°F Rain coming The owner of a chain of mini-markets wants to compare the sales performance of two of her stores, Store 1 and Store 2. Though the two stores have been comparable in the past, the owner has made several improvements to Store 2 and wishes to see if the improvements have made Store 2 more popular than Store 1. Sales can vary considerably depending on the day of the week and the season of the year, so she decides to eliminate such effects by making sure to record each store's sales on the same 8 days, chosen at random. She records the sales (in dollars) for each store on these days, as shown in the table below.

R3.42. Internet speed Carsten, Matt, and Rainer designed an experiment to see how different environments affect the Internet speed around campus. They used their own Mac computer and a PC belonging to the school and tested each in two different libraries, the main and the science library. Other factors included Time of Week (weekday or week- end), Time of Day (before or after 5 PM), and how busy the computer was (running other jobs or not). The measured the time it took to download a 50 Mb file from the school course management system. a) Name the factors and levels. b) How many runs will they need to run all treatment levels? c) In what order should they perform all the runs?
Data in the table comes from the NASA Global Climate Change website. It gives the average globaltemperature, in Celsius, for the given year. Use both rows for your calculations. For this problem, youwill see how well year correlates with the average temperature.

A peanut company sells a mixture of two types of beans. The cheapest mixture contains 80% lean peanuts and 20% pithy beans, while the most expensive bean contains 50% of each type. Every week the company can earn 1,800 kg of lean peanuts and 1,200 pithy peanuts. How many kg of each mixture must be made to maximize profit if the profit is Rp. 100 for each cheap mixture and Rp. 150 from the expensive mixture?a. Formulate the problem?b. Finish with a graphic method?
Directions: Solve the following problems. 1. The proportion of students who passed an engineering examination was 80%. Students complained that they would have done better if they were allowed to use calculators. Later, a random sample of 90 students took this exam with calculators and 75 passed. Was this a significant improvement at 0.05 level? 2. It is claimed that the average time spent by employees on telephone calls is less than 6 minutes. In a study time spent on the telephone by its employees, a large office monitors a random sample of 25 employee calls and finds the mean length of this calls to be 5.8 minutes with a standard deviation of 1.4 minutes. Is the claim true at 0.05 level of significance?
A researcher takes a sample of 40 introverts and 40 extroverts and asks them to solve problems in either a crowded room or an uncrowded room. The researcher measures the number of problems solved (numbers can range from 0 problems solved to 25 problems solved). Here are the results Crowded Room Uncrowded Room Introverts M = 12 M = 18 Extroverts M = 18 M = 12 Does there appear to be a main effect of room? Does there appear to be a main effect of personality (introversion/extraversion)? Does there appear to be an interaction between room and personality?
The cost C and the revenue R for a brokerage firm depend on the number T of transactions executed. (Both C and R are measured in dollars.) It costs $710 per day to keep the office open, and brokers are paid an average of $24 per transaction. Also, $34 in fees are collected for each transaction.
