The cоntent оf the exаm is belоw. You mаy downloаd the exam as a pdf here. You must not share this file with anyone in the class. Especially while the exam is open. You may not post this exam anywhere else even after the class is completed. (8 points) For each situation described identify the population of interest. Also determine whether the value shown in bold is a statistic or a parameter. In a survey of college students, the average amount spent on textbooks during one semester was $42. A survey found that 13% of electric vehicle owners reported that public charging stations were readily available where they live. (12 points) A researcher is interested in the effects of exercise on sleep patterns. She recruits a panel of working Americans. To control for various factors, she asks each subject their age, height, weight, whether they smoke, and what state they live in. Then for a period of 6 months the panelists wear fitness watches that track how many minutes of strenuous activity they engage in on a daily basis. The watches also track the amount of time each subject sleeps at night. Identify the population of interest for this study. Is this study an experiment or observational study? List the variables stated in this question. Classify each variable as quantitative or categorical. For the quantitative variables state the most likely units used to measure the variable. (10 points) The General Social Survey has been conducted since 1972. It is a survey of English-speaking persons 18 years or over within the United States. The survey explores a wide variety of social issues.One background question is marital status. One year, 1018 respondents reported being married, 214 were widowed, 389 were divorced, 78 were separated, 661 were never married, and 12 did not respond.Make a frequency and relative frequency table summarizing the marital status variable. (8 points) There are two histograms sketched below. One depicts the distribution of age at death for a population of individuals who died of natural causes, such as heart disease or cancer. The other depicts age at death for a population of individuals who died from trauma, such as accidents, murder, or suicide. Both histograms use the same scale on the horizontal axis. Indicate which histogram is which. Briefly explain the features of the distributions that led to your conclusions. (8 points) For each variable described below choose the histogram that best matches the variable. Histograms can be matched to more than one variable. Briefly justify your choice. Scores on a hard exam for a class of students. Scores on an easy exam for a class of students. The machines that fill soda bottles are not perfect, there is some variation in how much soda gets poured into each bottle. The exact volume of soda is measured in a sample of 100 one-liter bottles. The machine is just as likely to under fill the bottles as to over fill. Consider distribution of ages of cars on the road. Most cars are newer. The longer a car lasts, the more likely it is to be taken off the road. A few older vintage cars still remain. (16 points) Max was troubleshooting his home Wi-Fi network. To test the connection, he used the ping command to measure the round-trip response time (in milliseconds) between his computer and his wireless router. The six measured response times were 6, 6, 5, 10, 9, and 24.You may use your calculator to make these computations but do not use any statistical functions. Do not use Google Sheets for this problem. I want to see that you can calculate these values from the formulas. Find the mean response time. Find the median response time. Find the sample standard deviation of the response times. (8 points) At Center Hospital there is some concern about the high turnover of nurses. A survey was done to determine how long (in months) nurses had been in their current positions. The responses in order from smallest to largest of 20 nurses were: Months of Service by Nurse. 2 5 8 8 11 12 14 20 23 23 25 26 27 28 31 36 36 42 76 131 Find the five-number summary (Min, Q1, Median, Q3, and Max) for this data set. (10 points) Babies born after a gestation period of 32–35 weeks have a mean weight of 2725 grams and a standard deviation of 650 grams.Babies born after a gestation period of 40 weeks have a mean weight of 3450 grams and a standard deviation of 480 grams.Suppose a 34-week old baby weighs 3650 grams. Suppose a 40-week old baby weighs 4075 grams. Compute the z-scores for each of these two babies. Which baby weighs less relative to the others in their gestation group? (5 points) A used car dealer has sixteen cars on the lot which have an average distance driven of 63,000 miles. A seventeenth car is brought on the lot. What is the mileage of this new car if the average goes down to 65,250 miles? (6 points) Below is the histogram describing the weighted average distance from each home to five major employment centers in Boston. Higher values indicate the home is farther from where the jobs are in the area. Is this histogram skewed left, symmetric, or skewed right? Which measure of center (mean or median) better describes this data? Which measure of spread (standard deviation, IQR, or range) better describes this data? (9 points) The boxplot below compares the highway gas mileage (miles per gallon) of hybrid car models by driveline type. A higher MPG value indicates better fuel efficiency. List the drive line types in order from smallest to largest median. List the driveline types in order from smallest IQR to largest IQR. Based on this boxplot, which driveline type should you choose if you want a fuel-efficient hybrid car and a wider selection of models? Briefly explain the feature of the graph that helped you make your choice. (6 points) In each part, identify whether the events A and B are Mutually Exclusive, Independent, or Neither. Note, “Mutually Exclusive” means the same as “Disjoint”. Briefly justify your choice. You roll a die twice. A = rolling a 5 on the first roll. B = rolling a 5 on the second roll. You reach into a small bag of M&Ms and pick two out, eating them as you pick. A = the first M&M is blue. B = the second M&M is blue. You select a subject at random for a COVID study. A = the subject has been vaccinated for COVID. B = the subject has not been vaccinated for COVID. Copy the following and fill in the blank with your name.
