I’m assuming the numbers are 2/3 and 3/4 so find the common denominator. 2/3x4=8/12 and 3/4x3=9/12 so 8/12+9/12= 17/12 or 1 and 5/12
Answer:
-24 feet.
Step-by-step explanation:
To find this, we need to multiply -8 and 3. This gets us -24. That means the coral reef is -24 feet. I hope this helps!
Exponential model 0.996. Yes, 0.996 is very close to 1
Lunch starts at 1:30. So 1/4 of 1 hour is 15 minutes. Subtract 1 hour or 60 minutes from 1:30, which equals 12:30. So you have 1/4 remaining, so subtract 15 minutes from 12:30, giving you a final answer of 12:15.
Answer:
a. There's a 95% chance that the true proportion is in the confidence interval.
Step-by-step explanation:
When we want to estimate a property of a population (a population's parameter), without surveying the population, we use samples.
Then, with the information of the samples we can calculate the statistics and infere properties about a population. This inferences obviously came with some uncertainty, depending on the properties of the sample and specially the sample size.
When we talk about confidence intervals, we use the statistic of the sample (in this case, the mean) to estimate a range of values it is expected to find the true mean of the population. The width of this interval depends on the sample standard deviation and the sample size.
The value of the confidence interval (95%, 99%, etc) represent the probabilty that the true mean is within this interval.
