Answer:
Step-by-step explanation:
Given that:
There are 600 residents in the survey.
And results gathered identify that among 230 who were smokers, 157 are reported to have diabetes and among the remaining nonsmokers, 50 reported diabetes.
The objective is to construct a two by two table from the given data:
Diabetes
Yes No Total
Smoking
Yes 157 230 - 157
= 73 230
No 50 370 - 50 600 - 230
= 320 = 370
Total 157 + 50 320+ 73
= 207 = 393 600
Answer:
For x = 3 then
Step-by-step explanation:
First we must consider the <em>“memoryless”</em> or <em>“forgetfulness”</em> property of the exponential distribution, which means that the likelihood of something happening in the future has no relation with past events.
Taking the above statement into account we have that the probability that T lasts more than a+b hours given that an event has lasted at least “a” hours equals the probability that T lasts more than “b” hours:
For our case we have:
To make calculations easier we resolve using the Exponential cumulative distribution, therefore:
Now, if x = 3 then,
So, we can say that the probability that our friend waits at least 3 hours for the alarm to ring is 36.8%
Negative 4 is the answer to the question
