Scores on an aptitude test are known to follow a normal distribution with a standard deviation of 32.4 points. A random sample of 12 test scores had a mean score of 189.7 points. Based on the sample results, a confidence interval for the population mean is found extending from 171.4 to 208 points. Find the confidence level of this interval. Margin of Error (ME)= ? Z-Score (Z-a/2)= ? Confidence Level= ?

Write mu for the mean of a Normal distribution. The value of the standard deviation is...

Write mu for the mean of a Normal distribution. The value of the standard deviation is unknown. We want to test H0: mu = 8 vs H1: mu > 8. A random sample of 15 observations is taken from this distribution, and the sample mean (x-bar) and sample standard deviation (s) are calculated. Then t = (x-bar - 8)/[s/square_root(15)] is calculated, and is found to equal = 1.85. At what levels of significance could we reject H0

A population of values has a normal distribution with mean of 165.7 and standard deviation of 60.2. a) Get the z-score for a value of 163. For this problem you use the z score formula z=x−μσz=x-μσ b) This z-score tells you how many the score of 163 is above or below the population mean μμ . c) Find the probability that a randomly selected value is greater than 163. Part 2 A population of values has a normal distribution with mean...
