Q1: As a project for his statistics class in Spring 2001, Ahmed was supposed to take arandom sample of 30 cars in the student parking lot and determine the make and year ofeach car.(a) Ahmed used a random-number table to get a random sample of 30 cars in the parkinglot. Suppose the lot is full and there are 950 parking places. Describe how he sampledthe 30 cars.(b) After getting his random sample, Ahmed found that eight cars were Chaverolets,seven were Fords, five were Toyotas, three were BMWS, three were Hondas, threewere Oldsmobiles, and one was a Cadillac. Make a table for these data, and draw abar graph. Draw a circle graph showing the percentage of the total number of carssamples(c) The model years for each of the 30 cars are shown here:96 9 9 95 97 86 92 96 97 89 9283 92 99 87 89 90 90 97 93 8893 95 84 95 76 96 88 99 95 93Make a frequency table, histogram, and a frequency polygon for these data (use fiveclasses). Describe the shape of the histogram.(d) Consider the data types: nominal, ordinal, interval, or ratio. In part (b), what type ofdata do we have? Could you make a histogram for these data? In part (c), what typeof data do we have? Could you organize these data in a circle graph?

Given information: A sample of 30 cars is given.

The state highway department is studying traffic patterns on one of the busiest highways in the state. As part of the study, the department needs to estimate the average number of vehicles that pass an intersection each day. One of the department’s officer (Officer A) claims that on average, more than 15,000 cars passing the intersection. On the other hand, Officer B claims that on average, 18,000 cars passing the intersection. Meanwhile, a random sample of 64 days gives a sample mean of 14,205 cars and a sample standard deviation of 1,010 cars. Test both claim at 0.05 level of significance. Use the critical value approach and show the complete calculation steps for each testing. Whose claim is true? a)Testing Officer A’s claim State the hypotheses, find critical value and state the decision rule, compute the test value, make decision, conclusion. b) Testing Officer B’s claim State the hypotheses, find critical value and state the decision rule, compute the test value, make decision,…

A biologist is studying the composition of birds on a lake and counts 61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons. From previous studies performed around the same time of the year, she expects 50% of the birds to be ducks, 23% to be geese, 12% to be cranes, 10% to be swans, and 5% to be herons. What are the expected and observed counts? Select one. Expected = 55 ducks, 25 geese, 13 cranes, 11 swans, and 6 herons Observed = 61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons Expected = 61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons Observed 55 ducks, 25 geese, 13 cranes, 11 swans, and 6 herons %3D Expected = 55 ducks, 25 geese, 13 cranes, 11 swans, and 6 herons Observed = 55 ducks, 25 geese, 13 cranes, 11 swans, and 6 herons %3D %3D Expected = 61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons Observed = 61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons
2. In a population it is estimated that 20% have a desired trait of interest for the researcher. The researcher wants to know how many people on average he has to draw from a population to get 2 people with the trait. Use rows 20-24 of the Random Number Table to carry out the simulation. Explain clearly how you set up the problem and report your findings. Answer:

A nationwide job recruiting firm wants to compare the annual incomes for childcare workers in Connecticut and California. Due to recent trends in the childcare industry, the firm suspects that the that the mean annual income of childcare workers in the state of Connecticut is greater than the mean annual income of childcare workers in California. To see if this is true, the firm selected a random sample of 10 childcare workers from Connecticut and an independent random sample of 10 childcare workers from California and asked them to report their mean annual income. The data obtained were as follows. 80°F Partly sunny Annual income in dollars Connecticut 42438, 52287, 46837, 49334, 52848, 52929, 57111, 51860, 44967, 52174 California 50998, 38334, 56804, 50919, 49446, 41141, 45717, 43963, 55156, 47295 LL D 144Hz Send data to calculator V The population standard deviations for the annual incomes of childcare workers in Connecticut and in California are estimated as 6300 and 6100,…
