1. Define a parameter. (Points: 5)A parameter is quantitative measurement. A parameter is a numerical measurement describing an aspect from a population. A parameter is a numerical measurement describing an aspect from a sample. A parameter is qualitative measurement. A parameter is a numerical measurement that never changes. 2. Identify the implied population in the information here. Government agencies carefully monitor water quality and its effect on wetlands (Reference: Environment Protection Agency Wetland Report EPA 832-R-93-005). Of particular concern is the concentration of nitrogen in water draining from fertilized lands. Too much nitrogen can kill fish and wildlife. Twenty-eight samples of water were taken at random from a lake. The nitrogen concentration (milligrams of nitrogen per liter of water) was determined for each sample. The variable in this information is nitrogen concentration (mg nitrogen/l water).(Points: 5)number of fish samples of water taken at random the wetlands nitrogen concentration (mg nitrogen/l water) in the entire lake government agencies 3. Give an example of population members that will be omitted in the following situation. There is a population of all 250 students in your large statistics class. You plan to obtain a simple random sample of 30 students by using the sampling frame of students present next Monday.(Points: 5)students absent on Monday students who were absent on Friday as they are likely to absent on Monday boys who are present on Monday girls who are present on Monday students who are going on a field trip on Tuesday 4. Use a random-number table to simulate the outcomes of tossing a quarter 9 times beginning at row 5, block 2. Assume that the quarter is balanced (i.e., fair) and an even digit is assigned to the outcome heads (H) and an odd digit to the outcome tails (T).65321 85623 10204 50218 20321 2231598532 91972 39800 45670 20510 1045192012 59826 35456 79289 91483 2975445652 98653 45863 36963 15326 7895245678 10100 91251 37041 13712 14672(Points: 5)T H T H H T H H T T H T H H T T H H T H T H H T T T T T H T H H H T H T T H T H H T T H T 5.

The director of the campus-computing center did a study to determine the patterns of student computer usage. He found that 15% of the total student computer hours occurred during the first 5 weeks of the term, 25% during the middle five weeks, and 60% during the last 5 weeks. Would a time-series graph of this data be appropriate? Give a reason for your answer. (Points: 6)No. A time-series graph is not ideal for data collected over periods of longer than a week. No. A time-series graph is not ideal for fewer than 10 events or categories of data. Yes. A time-series graph identifies the frequency of events or categories in increasing order of occurrence. Yes. A time-series graph would show how student usage of the computer lab varies during the term. Yes. A time-series graph represents data that make up parts of a whole. 10. It's not an easy life, but it's a good life. Suppose you decide to take the summer off and sign on as a deck hand for a commercial fishing boat in Alaska that specializes in deep-water fishing for ground fish. What kind of fish can you expect to catch? One way to answer this question is to examine the reports on ground fish caught in the Gulf of Alaska. The following list indicates the types of fish caught annually in thousands of metric tons: flatfish, 36.3; Pacific cod, 68.6; sablefish, 16.0; Walleye Pollock, 71.2; rockfish, 18.9. Make a Pareto chart showing the annual harvest for commercial fishing in the Gulf of Alaska. (Points: 6)11.
