Use the following screenshot of a 95% confidence interval constructed using a TI-84 calculator for parts a and band for exercise 14. -PTORZINE (.61362.7064) P=.6600 n=400.0000 a. What is the margin of error for this confidence interval? (3 points) b. How many of the 400 trials were successes? (3 points)
Suppose you construct a 95% confidence interval estimate of the true population mean by conducting a random sample of size n=100. Your sample mean x (with a bar over it) = 80.5 and your calculated maximum error of the estimate is E = 3.5. What does this suggest? Circle answer. a. in 5% of all samples of this size, the mean is more than 84, b. in 95% of all samples of this size, the mean is at least 77,...
Assuming that the population is normally distributed, construct a 95 % confidence interval for the population mean, based on the following sample size of n=8. 1, 2, 3, 4, 5, 6, 7 , and 19 In the given data, replace the value 19 with 8 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval, in general. Find a 95% confidence interval for the population mean, using...
Assuming that the population is normally distributed, construct a 95% confidence interval for the population mean, based on the following sample size of n=8.1, 2, 3, 4, 5, 6, 7, and 24 In the given data, replace the value 24 with 8 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval, in general.Find a 95% confidence interval for the population mean, using the formula or technology.Round answer to two decimal places

Assuming that the population is normally distributed, construct a 95% confidence interval for the population mean, based on the following sample size of n = 5. 1, 2, 3, 4, and 30 In the given data, replace the value 30 with 5 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval, in general. Find a 95% confidence interval for the population mean, using the formula or...
Concept 4. Consider the following statement about a 95% confidence interval (CI) for the parameter p and enter the correct answer for the blank. If the sample size were increased to n 1000 then the confidence interval would be the confidence interval computed from a sample with n 64. A. Narrower than B. Wider than C. The same size as Concept 5. Consider the following statements for 10 non-negative numbers with mean 100. Select the letter(s) of each statement that...
