Answer:
<em>First option: </em>
Step-by-step explanation:
Given the point-slope equation , you need to solve for
, because you are looking for the equation of the line in slope-intercept form:
Being the slope of that line, and
the intersection of the line with the y-axis.
Then:
Apply Distributive property:
Subtract 7 from both sides:
Rewrite the equation:
(The linear function of the First option)
Answer:
It is a good Estimator of the Population Mean because the distribution of the sample midrange is just same as the distribution of the random variable.
Step-by-step explanation: from the table,
Minimum value = 34
maximum values = 1084
The sample mid-range can be computed as:
(Min.value + max.value)/2
(34 + 1084)/2
Sample mid-range = 55
The sample midrange uses only a small portion of the data, but can be heavily affected by outliers.
It provides information about the skewness and heavy-tailedness of the distribution which is just same as the distribution of the random variable.
The nature of this distribution is not intuitive but the Central Limit in which it will approach a normal distribution for large sample size.
