Given that the mean distribution is 217, and the median is 291. This follows that given 217<291, it implies that most of the values lie to the left of the center of the distribution, hence the distribution will be positively skewed.
Hence,
the answer is:
<span>b.) it is positively skewed </span>
Answer:
35°
Step-by-step explanation:
We assume that points S, T, U, V all lie on the circle.
Inscribed angle TUV intercepts long arc VST and short arc VUT. The long arc has measure 220°, so the measure of the short arc is 360° -220° = 140°.
Since chords UV and UT are the same length, point U bisects arc VUT. That means the measure of arc VU is 140°/2 = 70°.
Inscribed angle VSU intercepts arc VU, so has half the measure of the arc:
∠VSU = 70°/2
∠VSU = 35°

Step-by-step explanation:
Answer:
Normally distributed with a mean zero.
Step-by-step explanation:
In multiple regression analysis, residuals
should be Normally distributed with a mean zero.
In general, multiple regression is a technique to find more about the connection between many independent variables and dependent variables. It is simple a modern approach of a simple linear regression.
