The correct answers are A and E.
The mean is affected by outliers.
It a data set is skewed to the right, the mean will be larger than the median because the median is in the middle so will fall in the lower range while the mean is an average of all of the values, so the skewness pulls the mean toward the right, toward higher values.
There are 4 quarts in on gallon (hence "quart"). So from here it is simple multiplacation. 4 x 7 = 28. So you get 28 quarts of peas.
Answer:
A sample size of 128 is needed.
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(square root of the variance) and n is the size of the sample.
How large should a sample be if the margin of error is 1 minute for a 93% confidence interval
We need a sample size of n, which is found when 
. We have that 
. So
Rounding up
A sample size of 128 is needed.
Answer:
125 sit ups
Step-by-step explanation:
well if you divide 60 by 12 you get five and if you multiply 25 and 5 you get 125
