Step-by-step explanation:
Scientific notation : 6.04 * 10^-5.
Answer:
See below
Step-by-step explanation:
A 90% confidence interval is centered at a parameter and is 90% sure to contain the statistic.
When you are running a statistical test, you can create a confidence interval centered at the appropriate parameter (such as the mean) to see if the statistic stated in your null hypothesis is true if it's contained in the interval. Whatever the confidence level is determines how wide the interval will be, and as such, will determine how likely the interval will catch the statistic in question.
Answer:
y=-13
Step-by-step explanation:
5-y=18
-5 -5
-y=13
*-1 *-1
y=-13
- The distribution is skewed left.
- The median is an accurate measure of center.
- The interquartile range is an accurate measure of spread.
<h3>How to find the Distribution of data?</h3>
Probability plots might be the best way to determine whether your data follow a particular distribution. If your data follow the straight line on the graph, the distribution fits your data. This process is simple to do visually. Informally, this process is called the “fat pencil” test.
For skewed distributions, it is quite common to have one tail of the distribution considerably longer or drawn out relative to the other tail.
As, it is known that, when the distribution of data is left-skewed, the mean is less than median.
- In any research of distribution, the distribution is described by its shape. If there are more higher values than lower values, the distribution is skewed left.
- The distribution can be described by its center. If the distribution is skewed left or right, the median is an accurate measure of center.
- The distribution can be described by its spread. If the data set does not have an outlier, the interquartile range is an accurate measure of spread.
