Answer:
A) Mean = 1.0295
Median = 1.006
B) the largest sample Observation can be reduced to 1.3735
Step-by-step explanation:
A) I) The mean Value is the addition of all the values, then dividing by the number of values occured.
0.736 + 0.863 + 0.865 + 0.913 + 0.915 + 0.937 + 0.983 + 1.001 + 1.011 + 1.064 + 1.109 + 1.132 + 1.140 + 1.153 + 1.253 + 1.397 = 16.472
16.472 ÷ 16 = 1.0295
1.0295 is the mean value
II) The median value is the value at the center of the point. We have two values at the middle point.
(1.001 + 1.011) ÷ 2 = 1.006
1.006 is the median value.
Therefore the mean value which shows the actual middle value of the numbers if the numbers where evenly distributed is greater than the median value which show middle value of the numbers in the result.
The difference between them is
1.0295 - 1.006 = 0.0235
B) The largest sample Observation is 1.397. it can be decrease by subtracting the difference between the mean and median from the number.
Wherefore; the difference between mean and median is 0.0235
Therefore;
1.397 - 0.0235 = 1.3735
If the largest sample Observation is reduced to 1.3735, the median value will not be affected.
Answer:
At 5:15 PM , they will ring together.
Step-by-step explanation:
We have been given that first bell rings every 15 minutes and second bell rings at every 25 minutes.
In order to find when both will ring together again, we can find the LCM of these two numbers.
15 = 3 × 5
25 = 5 × 5
Therefore, LCM of these two numbers is
LCM = 5 × 5× 3
LCM = 75
Hence, 75 minutes = 75/60 = 5/4 hours
Therefore, at 5:15 PM , they will ring together.
