1. Is there a linear relationship between the median income and median age? (Round your answer to 3 decimal places.)

2. Which variable is the "dependent" variable?

• Median Age

• Median Income

1. c-1. Use regression analysis to determine the relationship between median income and median age. (Round your answers to 2 decimal places.)

1. c-2. Interpret the value of the slope in a simple regression equation. (Round your answers to 2 decimal places.)

4. Include the aspect that the county is "coastal" or not in a multiple linear regression analysis using a "dummy" variable. (Negative amounts should be indicated by a minus sign. Round your answers to 2 decimal places.)

5. Test each of the individual coefficients to see if they are significant. (Negative amounts should be indicated by a minus sign. Leave no cells blank - be certain to enter "0" wherever required. Round your answers to 2 decimal places.)

Required information Problem 9-5A Computing and analyzing times interest earned LO A1 [The following information applies to the questions displayed below.] Shown here are condensed income statements for two different companies (assume no income taxes). Miller Company Sales $ 1,000,000 Variable expenses (80%) 800,000 Income before interest 200,000 Interest expense (fixed) 60,000 Net income $ 140,000 Weaver Company Sales $ 1,000,000 Variable expenses (60%) 600,000 Income before interest 400,000 Interest expense (fixed) 260,000 Net income $ 140,000 Problem 9-5A Part 5 5.

Sixty-four students in an introductory college economics class were asked how many credits they had earned in college, and how certain they were about their choice of major. At α = .02, is the degree of certainty independent of credits earned?

(a) At α = .02, the hypothesis for the given issue is H₀: Credits Earned and Certainty of Major are independent.

• Yes

• No

(b) Calculate the chi-square test statistic, degrees of freedom, and the p-value. (Round your test statistic value to 2 decimal places and the p-value to 4 decimal places.)

(c) Find the critical value of the chi-square for α = .02. (Round your answer to 2 decimal places.)

Critical value        

Build an Earned Value Management (EVM) model using these variables:

Planned Value: $45,000

i.Note for understanding, this based on time, and what we expected to use based on time.  Your schedule variance is based on earned and planned.

Actual Cost: $39,500

Earned Value (how much has been spent based on planned costs) : $43,500

i.Note for understanding, this usually based on expected costs at the task level.  In other words, for the tasks complete the project was expected to use this much costs. Your cost variance is based on actual and earned.

Balance at Completion: $172,000

Original Time in Months: 14

Calculate in the model:

Cost Variance

Schedule Variance

Cost Performance Index

Schedule Performance Index

Estimate at Completion

Estimated Time

Use conditional formatting to render any “bad” values red, “good” values green and “0” values yellow.  Do cell by Cell.

Analyze the data and denote your evaluation of the project.  Include in the evaluation comments on schedule, costs, and performance

You will need the following variables:

ExamAvg, FinalExam, Partication, AssignAvg, MyName, Grade

Create lists for Exams and Assignments, ExamList and AssignList.

Assume Participation is 100% for now and assign values to assignments and exams (you'll have to guess at Exam2). Use methods we have learned on lists to calculate the averages.  

Your grade is calculated by the following weighting formula:

Grade = (0.30)*(ExamAvg) + (0.25)*FinalExam + (0.05)*Participation + (0.40)*AssignAvg

Use a series of if-else, and elif statements to calculate (and print) your grade according to the following:

if 90 <= grade <= 100 Congratulations, MyName, you earned an A.  

if 80 <= grade <= 89 Good work, MyName, you earned a B.

if 70 <= grade <= 79 You earned a C, MyName, perhaps a bit more work?

if 60 <= grade <= 69 You earned a D, MyName, come for help if you need it.

if grade < 60 You are failing the course. Please come for help.  

You are free to use different variable names, put values in a list, etc.  

Q. 1) Generally, in 2016, which of the folloing events will trigger the Employer Shared Responsability Penalty?

a) A part-time employee who works for employer with 50 or more employees, receives qualified health insurance from the Marketplace, and receives the premium tax credit.

b) A full-time employee who works for employer with 50 or more employees, receives qualified health insurance from the Marketplace, and receives the premium tax credit

c) A part-time employee who works for an employer with fewer than 50 employees, receives qualified health insurance from the Marketplace, and receives the premium tax credit.

d) A full-time employee who works for employer with fewer than 50 employees, receives qualified health insurance from the Marketplace, and receives the premium tax credit.

Smoking habits of UK residents: A survey was conducted to study the smoking habits of UK residents. Below is a data matrix displaying a portion of the data collected in this survey. Note that "£" stands for British Pounds Sterling, "cig" stands for cigarettes, and "N/A" refers to a missing component of the data.

a) What does each row of the data matrix represent?

• a variable
• an observation

b) How many participants were included in the survey?
c) Identify each variable, determine whether each variable is numerical or categorical. If the variable is numerical, specify continuous or discrete. If the variable is categorical, specify whether the variable is ordinal or not.

• The variables are sex (regular categorical), age (discrete), marital status (regular categorical), earnings (ordinal), whether or not the individual smokes (regular categorical), amount the individual smokes per day on a weekday (discrete), amount the individual smokes per day on a weekend (discrete)

Describe the common features shared by GPCRs and RTKs in their signaling mechanisms, focusing on how they are able to amplify signals. Specifically, how is the signal from one binding event (i.e., the binding of one ligand molecule to an individual receptor) propagated and strengthened?

Describe one difference in how GPCRs and RTKs transform extracellular signals into intracellular responses.

HCI 314- Public Health Informatics [21300] Although there are several EHR implementations in the Kingdom, collecting the granulated data from individual patients, there is an immense need of integration systems to speak between the EHRs and to produce aggregated data on which the public health professionals are mostly interested. Explain the importance of these integration systems in the Kingdom of Saudi Arabia?
