Answer:
the ones are options 2 and 3
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.

Answer:
The mean is 11.5
The median is 6
Step-by-step explanation:
First put all the terms in order from smallest to largest
2, 3, 5, 6, 6, 7, 8, 55
The mean is the average. To figure the mean add all the terms together and divide by the number of terms.
There are 8 terms
2+3+5+6+6+7+8+55=92
92/8=11.5
The median is the middle of all the terms. To figure the median find the middle two terms and find their average.
Hint: If the middle two terms are the same number, the median is that number.
The middle two terms are 6 and 6 so the median is 6
