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:

Researchers wanted to know the effectiveness of a new allergy medicine.  A study was conducted on 500 adults who experience allergy symptoms.  Each adult was randomly assigned to receive the new allergy medicine or a placebo.  Researchers recorded whether or not their symptoms improved within 1 week. a.   Complete the two-way table summarizing the findings.   Allergy Medicine Placebo Total Symptoms Improved  85 80   Symptoms DidNot Improve         Total 215    285 500    b.  Use the study results to complete the following.  Round your answer to the nearest tenth of a percent, as needed. Notice the percent sign is already included, so you just need to type the number.  What percent of the adults in this study were given the new allergy medicine?  % What percent of those who experienced improvements received the allergy medicine?   %  What percent of those who received the allergy medicine experienced improvements?   %  What percent of those who did not received the allergy…

Tch Generally, 1 in 40 women will develop skin cancer in their lifetime. A study showed that that the use of tanning beds increased a woman's risk of skin cancer by 50%. a. Write the risk factor of 1 in 40 women as a natural frequency out of 1000 American females: women out of 1000 women will develop skin cancer in their lifetime. Write this answer in Blank 1. b. If every American woman used tanning beds, find the number out of 1000 that would develop skin cancer in their lifetime. Round to the nearest whole number. Write this answer in Blank 2. Make sure you write down any work, calculations, or reasoning that you used to get to your solution. Blank #1 25 Blank #2 S I G A A

The Hill of Tara is located in south-central Meath, not far from Dublin, Ireland. Tara is of great cultural and archaeological importance, since it is by legend the seat of the ancient high kings of Ireland. For more information, see Tara: An Archaeological Survey, by Conor Newman, Royal Irish Academy, Dublin. Magnetic surveying is one technique used by archaeologists to determine anomalies arising from variations in magnetic susceptibility. Unusual changes in magnetic susceptibility might (or might not) indicate an important archaeological discovery. Let x be a random variable that represents a magnetic susceptibility (MS) reading for a randomly chosen site on the Hill of Tara. A random sample of 120 sites gave the readings shown in the table below. Magnetic Susceptibility Readings, centimeter-gram-second x 10-6 (cmg x 10-6) Magnetic Susceptibility 0 < x < 10 10 < x < 20 20 < x < 30 30 < x < 40 40 < x Number of Estimated Comment Readings 30 Probability = 0.25 "cool" 30/120 54/120…

The valence of a song is measured from 0 to 10 and detects the musical positiveness conveyed in the song. Tracks with high valence sound more positive (e.g. happy, ch with low valence sound more negative (e.g. sad, depressed, angry). The valence was computed for 42,000 songs on Spotify in the genres of Techno, Techhouse, Trance, Trap, Psytrance, DnB, Hardstyle, Underground Rap, Trap Metal, Emo The table below shows the number of songs with a given valence measurement.

The scatter plot suggests a steady,---Select--- with a ---Select--- slope. (b) Find the linear model that gives the number of songs with a given valence, where v is the valence, for 0 ≤ v ≤ 10. (Round all values to two decimal places. L(v) = ---Select--- C (c) The constant rate of change for the model is (d) Use the…
