Answer: Hello below is the complete question
A survey of entrepreneurs focused on their job characteristics, work habits, social activities, leisure time, etc. One question put to each entrepreneur was, "What make of car (U.S., Europe, or Japan) do you drive?" The responses (number in each category) for a sample of 100 entrepreneurs are summarized below. The goal of the analysis is to determine if the proportions of entrepreneurs who drive American, European, and Japanese cars differ.
U.S. Europe Japan
40 35 25
In order to determine whether the true proportions in each response category differ, a one-way chi-square analysis should be conducted. Suppose the p-value for the test was calculated to be p=0.1738 . What is the appropriate conclusion to make when testing at α = 0.10?
Answer : The conclusion to be drawn is that We cannot reject the Null hypothesis if we use a one-way chi square analysis because at α = 0.1 from the chi-square tabulated p-value = 0.584 while the calculated /given p-value is = 0.1738
Explanation:
Data given:
p-value = 0.1738
α = 0.10
sample size = 100
U.S cars = 40, Europe cars = 35, Japan cars = 25
The conclusion to be drawn is that We cannot reject the Null hypothesis if we use a one-way chi square analysis because at α = 0.1 from the chi-square tabulated p-value = 0.584 while the calculated /given p-value is = 0.1738
Answer:
b. 0.67
Explanation:
UCL = 1 + 0.10
= 1.10 inch
LCL = 1 - 0.10
= 0.9 inch
standard deviation = 0.005 inch
mean = 1 inch
Cpk
= min[(UCL - mean)/(3*standard deviation) , (mean - LCL)/(3*standard deviation))]
= min[(1.10 - 1)/(3*0.05) , (1 - 0.9)/(3*0.05))]
= min[0.67 , 0.67]
= 0.67
Therefore, Theprocess capability index (Cpk) if the long-run process mean is 1 inch is 0.67
The ten step cycle that results in the timely payment for patients' medical services is the MEDICAL DOCUMENTATION BILLING CYCLE.
Medical billing is a payment method that is used in USA health system. The medical billing process is an interaction between the healthcare providers and the insurance companies who are responsible for payments of medical services rendered to their clients.
