If a variable is significant, what F> |t| values are seen ? how does this number relate to the confidence interval?

How does the confidence interval relate to the significance level?
Explain what "95% confidence" means in a 95% confidence interval. What does "95% confidence" mean in a 95% confidence interval? A. If 100 different confidence intervals are constructed, each based on a different sample of size n from the same population, then we expect 95 of the intervals to include the parameter and 5 to not include the parameter. B. The probability that the value of the parameter lies between the lower and upper bounds of the interval is 95%....
What is significant about homonuclear diatomic molecules and how does paramagnetism and diamagnetism relate to it? Where does bond order and orbital mixing come into this? What is the significance of orbital mixing? I know this is a lot but I'm trying to put the whole section together into making sense. Thanks!
how to determine what confidence level to use when constructing a confidence interval for a 2 sample t test?
As the confidence level increase, how does the width of the confidence interval change (Width = Upper Limit – Lower Limit)? Why? Does it become more or less precise? can someone help me understand this please?
Describe the Confidence Interval 1. In two to three complete sentences, explain what a confidence interval means (in general), as though you were talking to someone who has not taken statistics. 2. In one to two complete sentences, explain what this confidence interval means for this particular study. 3. Construct a confidence interval for each confidence level given. Confidence level EBP/Error Bound Confidence Interval 50% 80% 95% 99% Table 8.7 4. What happens to the EBP as the confidence level...
Which of the following does NOT correctly describe how the width of a confidence interval for a population mean changes when the population standard deviation is known? The interval changes if the sample size decreases. The interval changes if the sample size increases. The interval narrows if the sample size increases and confidence level stays the same. The interval widens if the sample size decreases and the confidence level stays the same. The interval widens if the sample size stays...
Determine whether the random variable is discrete or continuous. In each case, state the possible values of the random variable. (a) The number of points scored during a basketball game. (b) The amount of rain in City B during April. (a) Is the number of points scored during a basketball game discrete or continuous? A. The random variable is discrete. The possible values are x≥0. B. The random variable is continuous. The possible values are x =0, 1, 2..... C. The random variable is discrete. The...
Suppose that a continuous random variable takes on the interval from 0 to 4 that the graph of its probability density is given the blue line of Figure 7.19 on values on the interval fr t 7.2 Suppose that a continuous random variable takes on values 0 to 4 and that the graph of its probability density is given by the blue tr to e line Figure 7.19. (a) Verify that the total area under the curve is equal to...
Q1. Building Confidence Intervals. The 90th percentile confidence interval for the number of active connections on a web server is given by the interval [15 ± 1.5]. This confidence interval was computed using 36 observations of the web server. Answer the following questions (stating any assumptions you make): (1) What is the standard deviation of the sample used to compute this confidence interval was? (2) What is the probability that the true mean of the number of active connections on...
