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.

Answer:
The surface area is 339.5 
Step-by-step explanation:
The surface area of a 3-dimensional shape is calculated by adding the areas of each side together, which would be 24.5 + 52.5 + 52.5 + 105 + 105 = 339.5 inches squared.
Answer:
37
Step-by-step explanation:
first you need to add 1 plus 4 which is 5. then square it so it becomes 25. Then using order of operations do 6 times 2 which is 12 and add it to 25 to get 37.
for the first one the answer is b. constant
and the for the second one b. term and product
The answer is (4/9)^11 since it is addition you add the powers however the fraction has to be the same in order for it to work same for division but division is subtraction
