- B. What is the best predicted temperature for a time when a bug is chirping at the rate of 3000 chirps per minute? The best predicted temperature when a bug is chirping at 3000 chirps per minute is____°F. C. What is wrong with this predicted value? The first variable should have been the dependent variable. It is unrealistically high. The value 3000 is far outside of the range of observed values. It is only an approximation. An unrounded value would be considered accurate. Nothing is wrong with this value. It can be treated as an accurate prediction.Give an example, other than those presented in this section, of a a. qualitative variable.b. discrete, quantitative variable.c. continuous, quantitative variable.hello, would you please help me check my answers and solve the other ones I didnt finish to the questions bellow? I really apreciate that! The table in attachment gives the data from historical election percent participation for the 18-24- year-old age group in US presidential elections from 1964 to 2012. For example the point (16, 40) represents the year 1980, x = 16 = 1980 – 1964, which had a participation rate of 40% for the 18-24-year-old age group in US presidential election. Type up your responses to the following 6 parts to this problem. There is no need to type the questions, just your responses, which can include screen shots. Create a scatter plot for the percent of participation of the 18-24-year-old group, y, as a function of years after 1964, x, using Desmos. See the video below for a review of how to create a scatter plot in Desmos. Create a linear model of the trend for the percent of participation of the 18-24-year-old group, y, as a function of years after 1964,…
- I'm a bit confused by the wording of step two in this project's procedure (posted below). My brain may be a bit fried at the moment but it sounds like it is asking for three variables (one categorical and two continous). Am I correct in thinking this? Procedure: Devise two research questions based on the variables in the Student Data Table. Identify the variables to be utilized. One should be categorical (which may be created from a continuous variable, i.e., variable months enrolled at TESU; Categories: less than one year and one or more years) and two should be continuous variables. Use descriptive statistics to describe the variables both numerically and graphically. Devise hypotheses for both research questions. Identify the appropriate statistical tests using alpha=0.05. Perform the statistical tests. Write up the results. Variables in the dataset: TESU school in which you are enrolled Arts and Sciences Applied Science and Technology Business and Management…Med-Tech labs is a facility that provides medical tests andevaluations for patients, ranging from analyzing blood samplesto performing magnetic resonance imaging (MRI).

- 24. In a study examining the relationship of coffee drinking and heart problems, the researcher reported that among 100 patients he studied from 5 area hospitals, those patients for treatment of heart problems drank an average of 2.7 cups of coffee per day while those patients being treated for other problems averaged only 1.4 cups of coffee per day. According to class, the variable "amount of coffee drank" is which of the following type in nature?
