Answer:
98% probability that at least one of Harold and Maude will make it to the cruise
Step-by-step explanation:
Independent probabilities:
When two events are independent, the probability of the two events happening simultaneously is the multiplication of each probability.
Probability that none makes it to the cruise:
Harold's flight has an 80% chance of making it, so 100 - 80 = 20% probability of missing.
Maude's flight has a 90% chance of making it on time, so 100 - 90 = 10% probability of missing.
Both missing: 0.2*0.1 = 0.02.
2% probability of both missing.
Probability that at least one makes it to the cruise:
Either both miss, or at least one makes it. The sum of the probabilities of these events is 100%. So
2 + p = 100
p = 98%
98% probability that at least one of Harold and Maude will make it to the cruise
Answer:
0.7325 to 5.6675 ug/dl
Step-by-step explanation:
The middle 90% will be 45% above the mean and 45% below the mean. This means
0.5-0.45 = 0.05 and
0.5+0.45 = 0.95
We use a z table. Look in the cells; find the values as close to 0.05 and 0.95 as we can get.
For 0.05, we have 0.0505 and 0.0495; since these are equidistant from 0.05, we use the value between them. 0.0505 is z=-1.64 and 0.0495 is z=1.65; this gives us z=-1.645.
For 0.95, we have 0.9495 and 0.9505; since these are equidistant from 0.95, we use the value between them. 0.9495 is z = 1.64 and 0.9505 is z=1.65; this gives us z = 1.645.
Now we use our z score formula,
Our two z scores are 1.645 and -1.645; our mean, μ, is 3.2; and our standard deviation, σ, is 1.5:
Multiply both sides by 1.5:
Add 3.2 to each side:
2.4675+3.2 = X-3.2+3.2
5.6675 = X
Multiply both sides by 1.5:
Add 3.2 to each side:
-2.4675+3.2 = X-3.2+3.2
0.7325 = X
Our range is from 0.7325 to 5.6675.
