Answer:2
Step-by-step explanation:
Answer:
B) The null hypothesis cannot be rejected since the test statistic is approximately t = .29,which is not in the rejection region.
Step-by-step explanation:
to calculate mean
14.25+ 13.7 +14.02
+14.13+ 13.99 +14.04
= 84.13/6
= 14.02167
average = 14
s = 0.1837
test statistics t:
(bar(x)-mu)/(s/√n)
= 14.02167-14/0.1837/√6
0.02167/0.1837/2.4495
= 0.02167/0.07499
=0.28897
this is approximately 0.29
<u>therefore B) The null hypothesis cannot be rejected since the test statistic is approximately t = .29,which is not in the rejection region.</u>

<span>5x−y=8 ; y = 5x - 8
7x+4y=22
substitute </span>y = 5x - 8 into 7x+4y=22
7x+4y=22
7x+4(5x - 8) = 22
7x + 20x - 32 = 22
27x = 54
x = 2
y = 5x - 8
y = 5(2)- 8
y = 10 - 8
y = 2
answer: x = 2 y = 2 or (2,2)
