Based on the information given, the correct options will be:
a.) Mary would use the sample standard deviation to calculate a t-statistic.
c.) The value for the degrees of freedom for Mary's sample population is six.
One-sample t-test simply means a statistical hypothesis test that's used for the determination of whether an unknown population mean will be different from the specific value.
In this case, the value of the degree of freedom for the sample will be:
= (n - 1) = 7 - 1 = 6.
Also, it should be noted that Mary would use the sample standard deviation to calculate a t-statistic.

Step-by-step explanation:
6 - 4s = - 8 - 6s
Bringing like terms on one side
-4s + 6s = - 8 - 6
2s = - 14
S = - 14/2
S = - 7
Answer:
1. Shen payed around $2.06 for the first bag of dog food.
2. Shen payed around $2.21 for the second bag of dog food.
Step-by-step explanation:
First, you have to do 14.98/7.26 to get around 2.06
Then, you do 17.54/7.94 to get around 2.21
Hope this helps!
Answer:
(x+3)^2 + (y-5)^2 = 4^2
or
(x+3)^2 + (y-5)^2 = 16
Step-by-step explanation:
The equation of a circle can be written in the form
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x--3)^2 + (y-5)^2 = 4^2
(x+3)^2 + (y-5)^2 = 4^2
or
(x+3)^2 + (y-5)^2 = 16
