The answer to your question is:
x^2 + 6/5x + 8/25;
Answer:
60
Step-by-step explanation:
The <em>correct answer</em> is:
The mean for July is smaller than the median; and
the mean for August is larger than the median.
Explanation:
A distribution with a positive skew would have a longer whisker in the positive direction than in the negative direction. A larger mean than median would also indicate a positive skew.
Alternatively, a distribution with a negative skew would have a longer whisker in the negative direction than in the positive direction. A smaller mean than median would also indicate a negative skew.
The whisker in the negative direction for July is longer than the whisker in the positive direction. This indicates a negative skew.
The whisker in the positive direction for August is longer than the whisker in the negative direction. This indicates a positive skew.
Answer:
18*2/3+12
Step-by-step explanation:
So, out of 18, she only uses 2/3, so it will be 18*2/3, plus the additional 12 she downloaded.
Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval is (29.6, 44.4).
<h3>What is a t-distribution confidence interval?</h3>
The confidence interval is:
In which:
is the sample mean.
- s is the standard deviation for the sample.
The critical value, using a t-distribution calculator, for a <u>two-tailed 95% confidence interval</u>, with 25 - 1 = <em>24 df</em>, is t = 2.0639.
The other parameters are given by:
.
Hence, the bounds of the interval are given as follows:
The 95% confidence interval is (29.6, 44.4).
