Multiply 2 hours by 7 to get to 14, so you multiply 410 by 7 to get to 2870 miles. 410/2 equals 210 miles per hour
Answer:
The minimum sample size required is 461.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
99% confidence level
So , z is the value of Z that has a pvalue of , so .
An interval estimate of the proportion p with a margin of error of 0.06. What is the minimum sample size required?
The minimum sample size required is n, which is found when M = 0.06.
We don't have an estimate for the true proportion, which means that we use . So
Rounding up
The minimum sample size required is 461.
Using the probability concept, it is found that there is a probability that she rolls a 1.
- A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
In a dice, there are 6 sides, one of which is a roll is 1, then:
There is a probability that she rolls a 1.
