Use a calculator to find the mean and standard deviation of these two sets of numbers: 4, 0, 1, 4, 2, 1 5, 3, 1, 6, 9, 2 Which data set is more variable? (Show hand calculations)
pick a number for mean and standard deviation generate 5 random numbers using a normal distribution and mean and standard deviation from (i) using your 5 numbers find the mean and the standard deviation of your data How far is your sample mean from your true mean? By 'far' I mean how many sample standard deviations. use the absolute value of distance here Repeat steps 2-4 1000 times. you should now have 1000 measures how far your sample mean is...
2 Applications of the Normal Distribution part 2 Calculate the Mean and Standard Deviation of a Normal Distribution Question Emma was told that her math test score was I standard deviation above the mean. If test scores were approximately normal with 77 and σ 8, what was Emma's score? not include units in your answer. For example, if you found that the score was 77 points, you would enter 77 Provide your answer below FEEDBACK MORE INSTRUCTION 5 6
9. Calculate the standard deviation of the class count data. For full credit you must show all of your work. The standard deviation should be no more than two significant figures. (15 pts) SD = . Sxa-)3 1-1 Write the meant standard deviation: L(2pts) Write the range of the standard deviation about the mean (3pts) 10. How precise were the counts? Explain using the standard deviation calculated. How does sample size contribute to a smaller standard deviation? (Spts) 11. Use...
Suppose you have the following data, with a mean and standard deviation of 5 and 2.1 3 3 4 5 7 8 If you were to subtract 2 from every observation, what change - if any- would you see in the transformed mean and standard deviation? the mean and standard deviation would decrease the mean wold stay the same but the standard deviation would decrease the mean and standard deviation would stay the same the mean would decrease but the...
