An exponential equation is a nonlinear regression equation of the form y= ab^x. Use technology to find and grab the exponential equation for the accompanying data, which shows the number of bacteria present after a certain number of hours. Include the original data in the graph. Note that this model can also be found by solving the equation log y= mx + b for y. Number of hours, x: 1 2 3 4 5 6 7 Number of bacteria, y:...
Use the data shown in the table that shows the number of bacteria present after a certain number of hours. Replace each y-value in the table with its logarithm, log y. Find the equation of the regression line for the transformed data. Then construct a scatterplot of left parenthesis x comma log y right parenthesis and sketch the regression line with it. What do you notice? Number of hours comma x 1 2 3 4 5 6 7 Number of...

can someone help me with this i am stuck with all these questions i dont get it Here are summary statistics for randomly selected weights of newborn girts: n = 155, X = 33.6 hg, 8 = 6.5 hg. Construct a confidence interval estimate of the mean. Use a 99% confidence level. Are these results very different from the confidence interval 31.3 hg <u <35.1 hg with only 13 sample values, x = 33.2 hg, and s = 2.3 hg?...
Evaluate the following integral using a change of variables. Sketch the original and new regions of integration, R and S. 1 y+2 x-y dxdy Sketch the original region, R, in the xy-plane. Choose the correct graph below. О в. О с. O D. O A. While any changes of variables are correct for this problem use the change of variables that makes the new integral the simplest by making u·x-y and v·y. Sketch the new region, S, in the uv-plane....
Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (The pair of variables have a significant correlation.) Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. The number of hours 6 students spent for a test and their scores on that test are shown below. (a) x=3hours (b) x=4.5hours (c) x=14hours (d) x=2.5hour Find the...
The Helicopter Division of Aerospatiale is studying assembly costs at its Marselles plant Past data indicates the accompanying data of number of labor hours per helicopter. Reduction in labor hours over time is often called a learning curve" phenomenon Using these dafa, apply simple linear regrescion and examine the residual plot. What do you conclude? Construct a scatter chart and use the Excel Trendline feature to identify the best type of curvlinear trendine (but not going beyond a second-order polynomial)...
