True or false: 1. When constructing a confidence interval for a sample Mean, the t distribution is appropriate whenever the sample size is small. 2. The sampling distribution of X (X-bar) is not always a normal distribution. 3. The reason sample variance has a divisor of n-1 rather than n is that it makes the sample standard deviation an unbiased estimate of the population standard deviation. 4. The error term is the difference between the actual value of the dependent...

Confidence Interval Given. Assume I created a 96% confidence interval for the mean hours studied for a test based on a random sample of 100 students. The lower bound of this interval was 3 and the upper bound was 16. Assume that when I created this interval I knew the population standard deviation. Using this information, (a) Calculate the width of the interval. (b) Calculate the margin of error for the interval. (c) Calculate the center of the interval. (d)...
