Answer:
$45 dinner = $9
$1 dinner = 45/9= 5
$60 dinner = 60/5=12
Hence he got $12 for a $60 dinner
12.74 divided by 13 is 0.98.
Hope that helped:)
Step-by-step explanation:
Consider the provided information.
Part (A) We need to find the confidence coefficient.
The given value or percentage of probability is known as the confidence coefficient that the interval contains the parameter.
Hence, the confidence coefficient is 0.90
Part (B) Practical interpretation of both of the 99% confidence intervals.
It means that there is 99% confident that the mean of population HRV for officers diagnosed hypertension which lies between 6.9 and 122.9
There is 99% confident that the mean of population HRV for officers those are not hypertensive which lies between 144.2 and 184.9.
Part (C)
If you are saying 99% confident that means the 99% of the similarly generated confidence intervals will contain the true value of the population mean in repeated sampling.
Part (D)
If We want to reduce the width of each confidence interval, you need to use smaller confidence coefficient.

Step-by-step explanation:
we have
<em>Felicia</em>
Apply distributive property
Combine like terms
Let
a ----> the missing term with coefficient x in Gregory's expression
b ----> the missing constant term in Gregory's expression
so
equate Gregory's expression to Felicia's expression
so
----->
------> 
so
Gregory's expression is
therefore
The missing terms are 2 and -x
