Preliminary data analyses indicate that you can consider the assumptions for using nonpooled t-procedures satisfied. Researchers obtained data on the number of acute postoperative days in the hospital using the dynamic and static systems. At the 10% significance level, do the data provide sufficient evidence to conclude that the mean number of acute postoperative days in the hospital is smaller with the dynamic system than with the static system?
Answers
Answer: hello some data is missing from your question attached below is the missing data
answer :
At 10% significance level ; critical value with the dynamic system = -1.3637
critical value with the static system = - 1.4759
hence the data provided is sufficient evidence that mean number of acute postoperative days in the hospital is smaller with the dynamic system
Step-by-step explanation:
At 10% significance level ; critical value with the dynamic system = -1.3637
critical value with the static system = - 1.4759
hence the data provided is sufficient evidence
Given ∝ = 0.10
i) mean number of dynamic system = ( x1 ) = 7.08
s1 ( std of sample ) = 1.51
sample size = 12
df ( degree of freedom ) = n - 1 = 11
Hence critical value : t∝,11 = -1.3637 ( = T.INV(0.1,11)
ii) mean number of static system
( x2 ) = 11.33
s2 ( std of static sample ) = 3.83
sample size = 6
df( degree of freedom ) = n -1 = 5
critical value = t∝,5 = -1.4759 ( = T.INV(0.1,5) )

21. Tom buys a DVD player on 12 monthly payments. The cash price is $600. He pays
* 10% deposit and the store charges 9% interest.
(a) How much is each payment?
(b) Total amount Tom pays for the DVD player?
Answers
Answer:
Each monthly payment is $ 49.05, and in total Tom paid $ 648.60.
Step-by-step explanation:
Given that Tom buys a DVD player on 12 monthly payments, whose cash price is $ 600, and he pays a 10% deposit and the store charges 9% interest, to determine how much is each payment and the total amount Tom pays for the DVD player the following calculations must be performed:
600 - 600 x 0.1 = 540
540 x 1.09 = 588.6
588.6 / 12 = 49.05
Thus, each monthly payment is $ 49.05, and in total Tom paid $ 648.60.

Answer:
Sometimes true: b. d.
Always true: a. e.
Never True: c. f.
Step-by-step explanation:
b. and d. depend on what value you put in, so that is sometimes true. Now a. and e. are always true because it is correct. C. and f. are never true because the equation does not make any sense.

How many triangles can be constructed with side lengths of 9.6 cm, 11.6 cm, and 21.2 cm?

NEED DIS ANSWER NOW PLZZZ
Answers
Answer: A) 0 triangles
============================================================
Explanation:
Adding up the two smaller sides gets us 9.6+11.6 = 21.2, but this result is not larger than the third side of 21.2
For a triangle to be possible, we need to be able to add any two sides and have the sum be larger than the third remaining side. This is the triangle inequality theorem.
I recommend you cutting out slips of paper with these side lengths and trying it out yourself. You'll find that a triangle cannot be formed. The 9.6 cm and the 11.6 cm sides will combine to form a straight line that is 21.2 cm, but a triangle won't form.
As another example of a triangle that can't be formed is a triangle with sides of 3 cm, 5 cm, and 8 cm. The 3 and 5 cm sides add to 3+5 = 8 cm, but this does not exceed the third side. The best we can do is form a straight line but that's not a triangle.
In short, zero triangles can be formed with the given side lengths of 9.6 cm, 11.6 cm, and 21.2 cm
