You can get higher confidence by involving yourself in something, such as a sport or hobby. Learning a new instrument, learning how to draw, playing a sport, volunteering or taking dance lessons are ways to improve your self confidence. It will show you that you can be good at something if you put your mind to it and practice. I've written an article on ways to improve self confidence and I've included the link in this answer.
What else can I help you with?
True or False The higher the confidence level the narrower the confidence interval?
True.
Which of the following helps explain why google's ipo was successful while 800 com's was not?
The timing of Google's IPO was much better as investor confidence was higher
This is a measurement of an arguments strength where the higher the confidence level the more likely the conclusion is true?
confidence level
What is a measurement of an argument strength where the higher the confidence level the more likely the conclusion is true?
Confidence level is a statistical measure that indicates the likelihood that a conclusion is true. It is expressed as a percentage, where a higher confidence level indicates a greater probability that the conclusion is accurate. A confidence level of 95%, for example, suggests that there is a 95% chance that the conclusion is true.
What happens to the confidence interval as the sample estimate increases?
Assuming that other measures remain the same, as the sample estimate increases both ends of the confidence interval will increase. In effect, the confidence interval will be translated to a higher value without any change in its size.Assuming that other measures remain the same, as the sample estimate increases both ends of the confidence interval will increase.

What happens to the width of a confidence interval as the value of the confidence coefficient is increased while the sample size is held fixed?
As the confidence coefficient increases, the width of the confidence interval also increases. This is because a higher confidence level requires a larger margin of error to ensure that the true population parameter is captured within the interval. Consequently, while the sample size remains fixed, the interval becomes wider to accommodate the increased uncertainty associated with a higher confidence level.
Is it true that the wider the confidence interval the less precise is the estimate?
All things being equal, a wider confidence interval (CI) implies a higher confidence. The higher confidence you want, the wider the CI gets. The lower confidence you want, the narrower the CI gets The point estimate will be the same, just the margin of error value changes based on the confidence you want. The formula for the CI is your point estimate +/- E or margin of error. The "E" formula contains a value for the confidence and the higher the confidence, the larger the value hence the wider the spread. In talking about the width of the CI, it is not correct to say more or less precise. You would state something like I am 95% confident that the CI contains the true value of the mean.

What is the impact on the size of the needed sample of changing from .01 confidence in meeting specified requirements to .05 confidence?
Changing from a 0.01 confidence level to a 0.05 confidence level typically reduces the required sample size. This is because a higher confidence level (0.01) indicates a stricter criterion for statistical significance, necessitating a larger sample to achieve the same power. Conversely, a 0.05 confidence level allows for a greater margin of error, thereby requiring fewer observations to detect an effect or meet specified requirements. As a result, the sample size can often be reduced when accepting a higher alpha level.
Do elite soccer players automatically have higher levels of confidence?
No they do not, elite soccer is much harder than the lower levels of soccer. I am an elite soccer player,and alot of times i don't have that confidence, same with my other teammates; that's whyy your couach is gonna make you go through alot of drills to build up that confidence.In elite soccer you wont just automatically have a higher level of confidence. ( your couach and you teamates will help build up that confidence.) :D
Why does the confidence interval become wider when the confidence level increases?
The confidence interval becomes wider when the confidence level increases because a higher confidence level requires a broader range of values to ensure that the true population parameter is captured within that interval. Essentially, increasing the confidence level means we want to be more certain that our interval includes the true value, which necessitates a larger margin of error. This trade-off between confidence and precision results in a wider interval. Thus, while we gain more confidence in the estimate, the precision of our estimate decreases.
what is the best way to have a smaller confidence interval?
To achieve a smaller confidence interval, you can increase the sample size, which reduces the standard error and narrows the interval. Additionally, using a higher confidence level leads to a wider interval, so opting for a lower confidence level can also help reduce the width. Lastly, ensuring a more precise measurement or reducing variability in the data can contribute to a smaller confidence interval.
