Description
Let's solve the exponential equation 4ex = 80.
(a) First, we isolate ex to get the equivalent equation | 804 | . |
(b) Next, we take ln of each side to get the equivalent equation | 804 | . |

Explanation & Answer
Thank you for the opportunity to help you with your question!
As it says, we start by dividing by 4 on both sides to get the "e" by itself.
e^x = 80/4; e^x = 20
Now we take the natural log of both sides.
x = ln(20) = 2.9957
Please let me know if you need any clarification. I'm always happy to answer your questions.Completion Status:

may assume that these respondents represent a simple random sample of
all potential respondents within the community and that the population
is large enough that application of the finite population correction
would not make an appreciable difference in the results. Item C in the description of the data collection
instrument lists variables 7, 8, and 9, which represent the respondent’s
general attitude toward each of the three shopping areas. Each of these
variables has numerically equal distances between the possible
responses, and for purposes of analysis they may be considered to be of
the interval scale of measurement.a. Determine the point
estimate, then construct the 95% confidence interval for = the average
attitude toward Springdale Mall. What is the maximum likely error in the
point estimate of the population mean?b. Repeat part (a) for and , the average attitudes toward Downtown and West Mall, respectively.Given
the breakdown of responses for variable 26 (sex of respondent),
determine the point estimate, then construct the 95% confidence
interval for = the population proportion of males. What is the maximum
likely error in the point estimate of the population proportion?Given
the breakdown of responses for variable 28 (marital status of
respondent), determine the point estimate, then construct the 95%
confidence interval for = the population proportion in the “single or
other” category. What is the maximum likely error in the point estimate
of the population proportion?

MATH 153 CCBC Inferences from Data on The Working Poor in the US Questions
There is a population of workers in this country who are employed but who do not earn enough in wages to securely cover the cost of their family’s basic needs. Although the numbers vary by state or district, these individuals and their families are similar in that they cross racial, cultural, and local boundaries. They are considered the nation’s “Working Poor.” This common graded assignment was designed to allow you, the Introductory Statistics student, to explore some data that may be related to this population. Through the use of multiple statistical concepts covered in your MATH 153 course you will complete the provided assignment below to demonstrate your understanding of the manipulation of data, the use of technology in statistical analysis, the relationships between related variables, estimating population parameters, and hypothesis testing.
