Answer:
B: The mean study time of students in Class B is less than students in Class A.
Step-by-step explanation:
To find out why answer B is the right answer, I will give you facts from each option.
Option A is false. <em>The mean study time in Class A is 4.8. Meanwhile in Class B it is 4. For Class A, sum up the 20 study times which is 96 and divide them by 20, you will get 4.8 hours of mean study time. For Class B, the sum of the 20 study times is 80, which divided by 20 will be 4.
</em>
Option B is True. <em>See previous explanation.
</em>
Option C is False. <em>The median study time in Class B is 4. The median study time in Class A is 4.8,
</em>
Option D is False. <em>The range in Class A is from 2 to 8. The range in Class B is from 2 to 7.
</em>
Option E is False: <em>The mean and median study time of these classes is different.</em>
Robins basket is heavier.
Teds basket: 5x7.25=36.25
Robins basket: 6x6.25=37.5
37.5-36.25= 1.25
It is heavier by 1.25 ounces or 1 and 1/4 ounces
$1.80 if the question was ( he would have 3/5 of the amount he started with)
198 + (199*3) + (200*2) +(201*5) + (202*2) = 2604
frequency = 1 + 3 +2 + 5 + 2 = 13
201 = (2604 + x )/14
multiply both sides by 14
x = 201*14 = 2604 +x
x = 2814 = 2604 +x
subtract 2604 from both sides:
x = 2814 - 2604
x = 210 cm
height of new player = 210 cm
