Assuming that the population (or sample) has a normal distribution, how many standard deviations above and below the mean contains 95% of the population (or sample)? Be precise!

Given the data set A = {9, 5, 16, 4, 32, 8, 12, 9, 11, 15, 5, 9, 18, 10}, which is the data of an entire population of subjects:
1. Calculate the arithmetic mean
2. Find the median
3. Find the mode
4. Calculate the range
5. Calculate the interquartile range
6. Calculate the mean deviation
7. Calculate the variance
8. Calculate the standard deviation

A population has a normal distribution with a mean of 51.5 and a standard deviation of 9.6. Assuming , the probability, rounded to four decimal places, that the sample mean of a sample of size 23 elements selected from this populations will be more than 51.15 is:

A population of values has a normal distribution with mean of 165.7 and standard deviation of...

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...

A random sample of size 16 from a normal distribution with known population standard deviation � = 3.1 yields sample average � = 23.2. What probability distribution should we use for our sampling distributions of the means? a) Normal Distribution b) T-distribution c) Binomial Distribution d) Poisson Distribution What is the error bound (error) for this sample average for a 90% confidence interval? What is the 90% confidence interval for the population mean?
