Answer:
Therefore, we are 95% confident that actual mean savings for a televisit to the doctor is within the interval of ($60.54 to $81.46)
Step-by-step explanation:
Let us find out the mean savings for a televisit to the doctor from the given data.
Using Excel,
=AVERAGE(number1, number2,....)
The mean is found to be
Let us find out the standard deviation of savings for a televisit to the doctor from the given data.
Using Excel,
=STDEV(number1, number2,....)
The standard deviation is found to be
The confidence interval is given by
Where the margin of error is given by
Where n is the sample of 20 online doctor visits, s is the sample standard deviation and is the t-score corresponding to a 95% confidence level.
The t-score is given by is
Significance level = α = 1 - 0.95 = 0.05/2 = 0.025
Degree of freedom = n - 1 = 20 - 1 = 19
From the t-table at α = 0.025 and DoF = 19
t-score = 2.093
So, the margin of error is
So the required 95% confidence interval is
Therefore, we are 95% confident that actual mean savings for a televisit to the doctor is within the interval of ($60.54 to $81.46)
Answer:
All raisins would be moving away from you at the same speed, without any dependence
Step-by-step explanation:
As you can see in the graph it is irrelevant if they are on one side or another of the cake since you would see everyone moving away from you at the same speed since the cake must undoubtedly expand to establish a distance of 3cm between the raisins .
Note: It should be understood that the dough should be uniform and the ideal cooking conditions for a standard cake
