Answer:
0.5996 is the probability that none contain high levels of contamination.
Step-by-step explanation:
We are given the following information:
We treat lab specimen containing high levels of contamination as a success.
P( lab specimen containing high levels of contamination) = 0.12
Then the number of lab specimens follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 4
We have to find the probability that none of the lab specimen consist of high level of contamination.
We have to evaluate:
0.5996 is the probability that none contain high levels of contamination.
Answer:
Step-by-step explanation:
3 minutes 59.1 seconds = (3*60) + 59.1 seconds = 180 + 59.1 seconds
=> 239.1 seconds
4 minutes 3.8 seconds = (4*60) + 3.8 seconds = 240 + 3.8 seconds
=> 243.8 seconds
4 minutes 1.6 seconds = (4*60) + 1.6 seconds = 240 + 1.6 seconds
=> 241.6 seconds
Mean = Sum of data / No. of Data
Mean = 239.1 + 243.8 + 241.6 / 3
Mean = 724.5 / 3
Mean = 241.5 seconds
<u>In Minutes and Seconds:</u>
= 241.5 / 60 = 4.025 minutes
= 4 minutes + 0.025 minutes
= 4 minutes + (0.025 * 60) seconds
= 4 minutes 1.5 seconds
