The biggest key here is identifying outliers. Outliers can pull measures of center either up or down drastically.Notice how the males have a VERY low outlier. This will pull the mean down severely and create a much larger range, or spread.The females have a median of about 12 hours, but have an upper extreme of 19, which compareatively is very high. This creates a larger range as well.
Answer:
<u><em>y = -(2/5)x+4</em></u>
Step-by-step explanation:
The 2 points are 0,4 and 5,2. If you want to find the equation, you need slope. slope = rise/run = -2/5.
y = mx + b. The b is the y intercept, so it's 4.
The equation is <u><em>y = -(2/5)x+4</em></u>
Answer:
Step-by-step explanation:
a) Out of 5, 1 only one is wrong. So number of questions answered correctly is (4/5)
To find the percentage, multiply (4/5) by 100

b) It is not possible to find the actual score because we don't know how many questions were there actually and the score for each question.
