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.
Hope this Helps!!!
Answer:
The first box is (3,2) the next one is (15,10), then mark the plot, make sure it's in a diagonal line. Mark (15,10) and (3,2) on the plot.
Step-by-step explanation:
A = 2s
c + 2s = 17 .....c + a = 17 (I subbed in "a" for 2s)
2c + a = 24
c + a = 17 .....(-1)
2c + a = 24
---------------
-c -a = -17...result of multiplying by -1
2c + a = 24
---------------add
c = 7
2c + a = 24
2(7) + a = 24
14 + a = 24
a = 24 - 14
a = 10
a = 2s
10 = 2s
10/2 = s
5 = s
so, senior tickets (s) cost $ 5, adult tickets (a) cost $ 10, and child tickets (c) cost $ 7
1 adult ticket + 1 senior ticket would cost $ 15
