Assume that a normal distribution of data has a mean of 20 and a standard deviation of 5. Use 68 - 95 - 99.7 rule to find the percentage of values that lie above 15. What is the percentage of values lie above 15?
Assume that a normal distribution of data has a mean of 12 and a standard deviation of 3. Use the 68-95-99.7 rule to find the percentage of values that lie below 9.
Assume that a normal distribution of data has a mean of 14 and a standard deviation of 2. Use the empirical rule to find the percentage of values that lie below 18.
If a variable has a distribution that is bell-shaped with mean 21 and standard deviation 5, then according to the Empirical Rule, 95.0% of the data will lie between which values? (This is a reading assessment question. Be certain of your answer because you only get one attempt on this question.) According to the Empirical Rule, 95.0% of the data will lie between _______ and______. (Type integers or decimals rounded to two decimal places as needed. Use ascending order.)
1. Suppose a variable has a normal distribution with mean 10 and standard deviation 2. Use the Empirical Rule to calculate the approximate PERCENTAGE area. What is the PERCENTAGE of values ABOVE 12? Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 27 is entered as 27.00, 3.5 is entered as 3.50, 0.3750 is entered as 0.38 |Enter PERCENTAGE in above blank with NO % sign. | 2. Suppose a variable has a...
Use the 68-95-99.7 rule to solve the problem. Assume that a distribution has a mean of 21 and a standard deviation of 4. What percentage of the values in the distribution do we ex between 17 and 217 25% 34% 68% ОО 17% Question 35 of 40
6. Assume that x has a normal distribution with the specified mean and standard deviation. Find the following probability: ?(10 ≤ ? ≤ 26); ? = 15, ? = 4 ___________________ Find the z-value such that 5.2% of the standard normal curve lies to the left of z. ___________________
1.Assume that a distribution has a mean of 21 and a standard deviation of 4. What percentage of the values in the distribution do we expect to fall between 17 and 21? 2. Suppose that the luxury sales tax rate in a foreign country is 27%. A very wealthy socialite bought a diamond tiara for $175,000. How much tax does she pay?
Use the 68-95-99.7 rule to solve the problem. Assume that a distribution has a mean of 29 and a standard deviation of 4. What percentage of the values in the distribution do we expect to fall between 29 and 377 25% 5% 47.5% 95%
If a variable has a distribution that is bell-shaped with mean 15 and standard deviation 3, then according to the Empirical Rule, 68.0% of the data will lie between which values? (This is a reading assessment question. Be certain of your answer because you only get one attempt on this question.) According to the Empirical Rule, 68.0% of the data will lie between __ and __.
