Solution :
We plot the given data using graphing calculator to get the best fit line of the model.
First we plot an exponential series of the data, shown in the graph below
The exponential series model is given .
i.e.
Here, a=5.958, k=-0.1.
Now, we plot an power series of the data, shown in the graph below
The power series model is given .
i.e.
Here, a=7.271, b=-0.52.
Now, we compare these two graph we seen that the best fit line curve is shown in exponential series.
Therefore, The equation of the model is exponential model .
Determine whether the exponential model y = a ekt or the power model y = a...
The data on the below shows the number of hours a particular drug is in the system of 200 females. Develop a histogram of this data according to the following intervals: Follow the directions. Test the hypothesis that these data are distributed exponentially. Determine the test statistic. Round to two decimal places.

1. Two manufacturing processes are being compared to try to reduce the number of defective products made. During 8 shifts for each process, the following results were observed: Line A Line B n 181 | 187 Based on a 5% significance level, did line B have a larger average than line A? *Use the tables I gave you in the handouts for the critical values *Use the appropriate test statistic value, NOT the p-value method *Use and show the 5...
