A researcher is forced to collect data from a smaller sample of individuals to test their research hypotheses than originally anticipated. This will have the effect of_ a. Reducing the expected distance between the sample mean and u O b. Reducing the expected value the mean (HMean) O c. Increasing the expected distance between the sample mean and u O d. Increasing the expected value of mean (HMean) All else constant, which combination of factors would increase the width of a confidence interval most? O a. a smaller sample size and a smaller confidence interval O b. a larger sample size and a smaller confidence interval C. a smaller sample size and a larger confidence interval O d. a larger sample size and a larger confidence interval All else constant, which of the following would not have an effect on the width of a confidence interval? O a. an increased sample mean O b. an increased sample size O C. an increased percentage of confidence O d. an increased sample variance Which of the following is true about a 95% confidence interval of the mean: a. 95 out of 100 confidence intervals will contain u. O b. 95 out of 100 sample means will fall within the limits of the confidence interval. O C. 95% of the time u will fall within the limits of the confidence interval. O d. There is a 0.05 probability that u falls within the limits of the confidence interval. Clear my choice In confidence interval estimation, what are we confident of? O a. That the interval includes the sample mean O b. That the interval includes O c. That the wider the interval the more likely it is to include u O d. That the interval will include 95% of all sample means drawn Clear my choice
