Step-by-step explanation:
To find a ratio, you have to divide a next terms with before terms.
A1 = 35/2
A2 = 7
ratio = A2 ÷ A1

ratio = 7 × 2/35
ratio = 14/35 = 0,4
Ratio = 0,4

Answer:
a) The test is left-tailed.
Step-by-step explanation:
a) Hypothesis testing is tagged two-tailled if the test checks for a claim in both directions (greater than and less than).
It is one tailed if it checks for a claim in only one direction (either greater than or less than). It is left-tailed of it is testing the claim in a less than direction and right-tailed if it is testing the claim in a greater than direction.
This question is to check results from a test of the claim that less than 8% of treated subjects experienced headaches. It is evidently left tailed.
