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>

It’s area because you don’t want the oil to go only around the pan. You want it all over the surface.
Answer:
Step-by-step explanation:
CosB = ((15^2) + (8^2) - (14^2)) / (-2(15)(8))
cosB = 93 / -240
Take inverse cosine:
113°
X=-2 I think my bad if u got it ring
