A virus, due to human error, escaped a research facility in an isolated island. A day after thebreach, 7 test subjects were found to be infected. On the sixth day, the count increased to 21infected. The number increased to 63 infected on the 11th day, 189 on the 16th day, and 567 onthe 21st day. If no intervention happened, create a regression model to quantify the infected testsubjects after "t" days, graph the function, and, determine the number of infected after 60 days.Use exponential regression model.

The regression equation is used to relate the response variable with one or more explanatory…

A study of king penguins looked for a relationship between how deep the penguins dive to seek food and how long they stay underwater. For all but the shallowest dives, there is a linear relationship that is different for different penguins. The study report gives a scatterplot for one penguin titled, “The relation of dive duration (DD) to depth (D).” Duration DD is measured in minutes, and depth D is in meters. The report then says, “The regression equation for this bird is, DD=2.69+0.0138D.is, DD=2.69+0.0138D.” According to the regression line, how long does a typical dive to a depth of 200200 meters last? The dives varied from 40 meters40 meters to 300 meters300 meters in depth. Use the regression equation to determine DD for D=40D=40 and D=300D=300 and then plot the regression line from D=40D=40 to D=300.to D=300. Give your answers to two decimal places.

Listed below are systolic blood pressure measurements (in mm Hg) obtained from the same woman. Find the regression equation, letting the right arm blood pressure be the predictor (x) variable. Find the best predicted systolic blood pressure in the left arm given that the systolic blood pressure in the right arm is 85 mm Hg. Use a significance level of 0.05. Right Arm 100 99 91 76 76 5 Left Arm 175 170 146 147 146 Click the icon to view the critical values of the Pearson correlation coefficient r The regression equation is y = +x (Round to one decimal place as needed.) Given that the systolic blood pressure in the right arm is 85 mm Hg, the best predicted systolic blood pressure in the left arm is mm Hg. (Round to one decimal place as needed.)
A real estate agent wanted to find the relationship between sale price of houses and the size of the house. Shecollected data on two variables recorded in the following table for 15 houses in Seattle. The two variables are PRICE= Sale price of houses in thousands of dollarsSIZE= Area of the entire house in square feet. The Excel working has been given. Note: the left hand side is Regression run(ans a).. The right hand side is 'new' regression run (for ans d). Question b) Interpret the slope and constant term with proper UNITS assigned. c) Comment on the explanatory power of the regression model from the required output. Copy that specificoutput into your assignment word document.Now to increase the explanatory power of the model the real estate agent decides to look at the age of thehouse and the garden size. For the 15 houses in our sample the new variables areAGE= Age of the house in years, since it was builtGARDEN= Area of the garden in acres. d) Once these two new variables are…
Suppose the following data were collected from a sample of 1515 CEOs relating annual salary to years of experience and the economic sector their company belongs to. Use statistical software to find the following regression equation: SALARYi=b0+b1EXPERIENCEi+b2SERVICEi+b3INDUSTRIALi+eiSALARY�=�0+�1EXPERIENCE�+�2SERVICE�+�3INDUSTRIAL�+��. Is there enough evidence to support the claim that on average, CEOs in the industrial sector have lower salaries than CEOs in the financial sector at the 0.010.01 level of significance? If yes, write the regression equation in the spaces provided with answers rounded to two decimal places. Else, select "There is not enough evidence."
