Answer:
See Explanation
Step-by-step explanation:
Given
Required
The median interval
The question is incomplete, as the required data is not given.
To solve this question, I will use the following assumed dataset.
First, calculate the median position.
This implies that the median is the mean of the 5th and 6th data
So, we have the interval to be.
<em>Generally, the median of 10 data set is located at interval 5 to 6</em>
Answer:
a) X can take the values {0,1,2,3,...,n}
The probability mass function of x is defined for k copies received correctly as:
b) N should be N=2 to ensure that with probability 0.99 at least one copy of the message is received.
Step-by-step explanation:
The variable X:number of copies received correctly by the end user can be modeled as a binomial variable, as it is a sum of n Bernoulli variables with probability p.
X can take the values {0,1,2,3,...,n}
The probability mass function of x is defined for k copies received correctly as:
being p: the probability that a packet is received correctly by an end user, and q=1-p: the probability that a packet is not received correctly by an end user.
b) We have to calculate n so as to have a probability P(x≥1)=0.99, when p=0.9.
