Answer:
A) 2.58
B) 1.96
C) 1.65
Step-by-step explanation:
A hypothesis used to test that

against the alternatives
not equal to 10
if null hypothesis is true, then distribution of test statics follow
for two sided alternatives hypothesis
, then P value is
(1)
a)significance level
from 1 eq we get
Therefore
FROM Z TABLE
B) significance level
from 1st equation we get
Therefore
FROM Z TABLE
C) significance level
from 1 eq we get
Therefore
FROM Z TABLE
The answer that would best complete the given statement above is Z-SCORE. <span>When a data value is converted to a standardized scale representing the number of standard deviations the data value lies from the mean, we call the new value a Z-SCORE. Hope this helps.</span>
Given the original dimensions of:
2 1/2 ft, 3 ft and 1 1/2
After addition of 1/2 ft on both sides, the new dimensions will be:
3 1/2 ft, 4 ft, and 2 1/2 ft
thus the volume of the the prism will be:
Volume=length*width*height
V=3 1/2×4×2 1/2
V=35 ft³
Answer: 35 ft³
To find the quotient of 95 and 3.25 we may do something like this:
95 ÷ 3.25 =
= 95 ÷ 3 1/4 =
= 95 ÷ 13/4 =
= 95 * 4/13 =
= 380/13 =
= 29 3/13
I hope it'll help you :)
Answer:
The 99% lower confidence bound for the true average weight loss is 3.98 pounds.
This means that we can be 99% sure that the mean weight loss for all obese adults on a low-carb diet is positive.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 11 - 6.02 = 3.98 pounds
The 99% lower confidence bound for the true average weight loss is 3.98 pounds.
This means that we can be 99% sure that the mean weight loss for all obese adults on a low-carb diet is positive.
