describe the general idea of a confidence interval. use any appropriate formula as an example. describe...
Of the following general derivations, choose the formula that you need for computing a confidence interval: Select one: a. Confidence interval = sample statistic + margin of error b. Confidence interval = sample statistic + standard deviation c. Confidence interval = population parameter + margin of error d. Confidence interval = population parameter + standard deviation
calculate the 95% confidence interval using the appropriate
formula for this sample size. Remember to add and subtract the
margin of error from the sample mean to calculate the lower and
upper bounds of the confidence interval. Please provide excel

When interpreting a confidence interval, it is appropriate to use the term probability. True or False?
Define confidence interval and degree of confidence. Provide at least one example of a confidence interval and interpret the result.
The formula used to compute a confidence interval for the mean of a normal population when n is small is the following. What is the appropriate t critical value for each of the following confidence levels and sample sizes? (Round your answers to two decimal places.) (a) 95% confidence, n = 17 (b) 90% confidence, n = 12 (c) 98% confidence, n = 24 (d) 90% confidence, n = 24 (e) 95% confidence, n = 13...

On a particular golf course, a sample of 40 golfers have a mean
golf score of 79. Suppose the population standard deviation for
this course is 3.6605.
(a) Using the formula a 90% confidence interval as
presented in lecture, fill in the blanks with the appropriate
values for this problem for calculating the confidence interval
below. To enter
where x is any number, type sqrt(x). For example,

When to Use What: For each example below you would start to construct a confidence interval by identifying which distribution should be used to find the margin of error. It is possible that you won't be able to use either distribution. (a) a confidence interval for a population proportion where n = 45 and there are 27 successes in your sample leading to a sample proportion of 0.600 t-distribution z-distribution neither distribution

The formula used to compute a large-sample confidence interval for p is p̂ ± (z critical value) p̂(1 − p̂) n What is the appropriate z critical value for each of the following confidence levels? (Round your answers to two decimal places.) 87%
In general, increasing the confidence level will narrow the confidence interval, and decreasing the confidence level widens the interval. a. True b. False ... GIVE ME THE CORRECT ANSWER DETAILED PLEASE!
