What happen to the width of a confidence interval if the sample size is doubled from 100 to 200?
When the sample size is doubled from 100 to 200, the width of the confidence interval generally decreases. This occurs because a larger sample size reduces the standard error, which is the variability of the sample mean. As the standard error decreases, the margin of error for the confidence interval also decreases, resulting in a narrower interval. Thus, a larger sample size leads to more precise estimates of the population parameter.
If you have a 87 percent then you get a 0 percent what will happen?
Your average will be 43.5 percent. You'll probably fail the course.
Are 50 percent odds really 50 percent?
Yes. They are exactly 50 percent. This doesn't necessarily mean that it will happen exactly half the time, only that if you ran the odds an infinite number of times it would be expected to happen 50 percent of the time.
Why can't probability be greater than one or less than zero?
Probabilities are given a value between 0 (0% chance or will not happen) and 1 (100% chance or will happen). You cannot have a negative percent for something that will not happen or a percent greater than 100 for something that will happen.
If something has probability 1000 percent is it sure to happen?
In the context of the usage 1000%, it would be sure to happen. As far as probability is concerned, the probability of certain is 1 or 100%.
When the sample size increase what will happen to the 95 percent confidence interval?
It becomes narrower.

It will decrease.It will decrease
What happen to confidence interval if increase sample size and population standard deviation simultanesous?
The increase in sample size will reduce the confidence interval. The increase in standard deviation will increase the confidence interval. The confidence interval is not based on a linear function so the overall effect will require some calculations based on the levels before and after these changes. It would depend on the relative rates at which the change in sample size and change in standard deviation occurred. If the sample size increased more quickly than then standard deviation, in some sense, then the size of the confidence interval would decrease. Conversely, if the standard deviation increased more quickly than the sample size, in some sense, then the size of the confidence interval would increase.
