Answer: between 9 and 10 but a little closer to teen than to nine
Step-by-step explanation: so the actual square root of 95 is 9.746794344808963 so round up to the nearest 10th which would be 9.7
Answer:
- the sample mean is 44
- the sample standard deviation is 12.35
Step-by-step explanation:
given information:
data, = 36.45, 67.90, 38.77, 42.18, 26.72, 50.77, 39.0, 50.23
the number of data, n = 8
the sample mean, xbar
xbar = ∑/n
= (36.45+67.90+38.77+42.18+26.72+50.77+39.0+50.23)/8
= 352.08/8
= 44
standard deviation, s
s =
=
=
= 12.35
In hypothesis testing the claim that we have to test always goes into alternative hypothesis. The null hypothesis is negation of claim.
Here the claim to be tested is James bond can taste the difference between a martini that is shaken and one that is stirred.
So negation of this claim is James bond can not taste the difference between a martini that is shaken and one that is stirred.
So the null hypothesis for given experiment is
Null hypothesis: James bond can not taste the difference between a martini that is shaken and one that is stirred.
Alternative hypothesis: James bond can taste the difference between a martini that us shaken and one that is stirred.
Answer:
r = 8.12
Step-by-step explanation:
The volume for a cylinder is V=πr^2h therefore,
v = 2279.64
h = 11ft
r = ?
2279.64 = πr^2 * 11
207.24 = πr^2
