The correct statement about the data set is:
Option: B
(B.)
On arranging the given data points in the increasing order we have:
14 16 19 19 20 20 21 21 22 22 23
- Minimum value of the data set=14
- Maximum value of data set=23
- Median or Middle quartile of data set i.e.
=20
- Lower set of data is:
14 16 19 19 20
Lower quartile or first quartile i.e. =19
- Upper set of data is:
21 21 22 22 23
Upper quartile or third quartile i.e. = 22
- Interquartile range(IQR) is calculated as the difference between the upper and the lower quartile.
i.e.
Hence, IQR=22-19=3
Hence, the correct statement is:

Answer:
a) The graph of the probability density function for flight time is shown below.
b) 1/2
c) 0
d) 130 minutes
Step-by-step explanation:
Let's deal with the flight times in minutes instead of hours, and let T be the random variable that represents the flight time. T is uniformly distributed between 120 minutes and 140 minutes. The probability density function for T is given by
for t in [120, 140]
a) The graph of the probability density function for flight time is shown below.
Delta Airlines quotes a flight time of 125 minutes for its flights from Cincinnati to Tampa.
b) The probability that the flight will be no more than 5 minutes late is given by
c) The probability that the flight will be more than 10 minutes late is given by
because the probability density function is zero for t outside of [120, 140]
d) The expected flight time is given by minutes
Answer:
The height of the building is 153.664 meter.
Step-by-step explanation:
Consider the provided function.
Here t represents the time v₀ represents the initial velocity, s₀ represents the initial height and s(t) represents the height after t seconds.
It is given that the splash is seen 5.6 seconds after the stone is dropped.
That means after 5.6 seconds height s(t) = 0, Also the initial velocity of the stone is 0.
Substitute respective values in the above function.
As height can't be a negative number so the value of s₀ is 153.664.
Hence, the height of the building is 153.664 meter.
