As suburban gardeners know, deer will eat almost anything green. In a study of pine seedlings at an environmental center in Ohio, researchers noted how deer damage varied with how much of the seedling was covered by thorny undergrowth.   Deer Damage Thorny cover Yes No None 60 151 <1/3 76 158 1/3 to 2/3 44 177 >2/3 29 176 Data provided by Patricia Heithaus and the Department of Biology at Kenyon College.   © Macmillan Learning What is the probability that a randomly selected seedling was damaged by deer? Give your answer to four decimal places. probability:

One common system for computing a grade point average​ (GPA) assigns 4 points to an​ A, 3 points to a​ B, 2 points to a​ C, 1 point to a​ D, and 0 points to an F. What is the GPA of a student who gets an A in a3​-credit course, a B in each of two 4​-credit courses, a C in a 4​-credit course, and a D in a 3​-credit course?

A nurse recorded the pain level of a sample of patients being treated for the same illness. Pain levels were recorded using one of the following: No pain, minor pain, moderate pain, severe pain. What terms can be used to classify the variable of interest in this study? OA. Categorical - Ordinal OB. Categorical - Nominal OC. Numeric - Discrete OD. Numeric - Continuous

A researcher records the gender of each child born in the county hospital during the month of June. This researcher is measuring a discrete variable. O True O False

The National Electronic Injury Surveillance System tracks injuries reported from hospital admissions across the United States (Consumer Product Safety Commission 2018). For the data in 2017, we extracted all incidences of hand injuries that referenced punching a wall. There were 1843 such cases. The surveillance system also records some of the properties of the patients, including gender. Of all cases where a person was admitted to a hospital for injuries from punching a wall, 1352 were recorded as male and 491 were recorded as female. a. Do an appropriate hypothesis test to ask whether the proportion of males among wall-punchers is 50%.

The results of this program are shown in the following table. The population change is the number of deer born minus the number of deer that died during that year. The herd population started at 2000 when this study began. Calculate the number of deaths (predation + starvation). To determine the deer population change, subtract the number of deaths from births (births - deaths), this can be a positive number, indicating growth, ora negative number which indicates a population decline. Calculate the deer population by adding/subtracting the population change from the population the year before The first row (1971) has been completed for you as an example. Graph the deer and wolf populations as two lines (color and label) Wolf Population Births Number of Deer Population deaths Year Deer Predation Starvation Deer Change Population 1970 starting population, data unknown for prior year. 2000 1971 10 800 400 100 500 +300 2300 1972 12 920 480 240 1973 16 1,000 640 500 1974 22 944 880 180 1975…
