(This is a multiple choice question)Suppose you are rehearsing for a dance competition and you fall and hurt your shoulder. At t
he hospital, they take X-rays, consult a shoulder specialist, and give you a stabilizer brace. You pay a $50 co-pay at the time of service, and the ER bills your insurance company for the rest. The total hospital bill is $3,720. The table below shows the payment structure for your health insurance policy. If the injury happened in July, what is your total paid in monthly premiums?

Answer:
a) For the first part we have a sample of n =10 and we want to find the degrees of freedom, and we can use the following formula:
d.9
b)
a.15
c) For this case we have the sample size n = 25 and the sample variance is , the standard error can founded with this formula:
Step-by-step explanation:
Part a
For the first part we have a sample of n =10 and we want to find the degrees of freedom, and we can use the following formula:
d.9
Part b
From a sample we know that n=41 and SS= 600, where SS represent the sum of quares given by:
And the sample variance for this case can be calculated from this formula:
a.15
Part c
For this case we have the sample size n = 25 and the sample variance is , the standard error can founded with this formula:
Answer: The coefficient of determination = 0.6291
Step-by-step explanation:
Given: Total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083.
The coefficient of determination is computed as:
Substituting given values, we get
Therefore, the coefficient of determination = 0.6291
