The mean SAT verbal score is 401, with a standard deviation of 97. Use the Empirical Rule to determine what percent of the scores lie between 207 and 498. (Assume the data set has a bell-shaped distribution.)
Solution:- Given that mean = 401, sd = 97
P(207 < X < 498) = P((207-401)/97 < Z < (498-401)/97))
= P(-2 < Z < 1)
= 0.8185
= 81.5%
The mean SAT verbal score is 401, with a standard deviation of 97. Use the Empirical...
The mean SAT verbal score is 478, with a standard deviation of 98. Use the Empirical Rule to determine what percent of the scores lie between 380 and 478. (Assume the data set has a bell-shaped distribution.)
The mean score of a competency test is 77, with a standard deviation of 4. Use the Empirical Rule to find the percentage of scores between 69 and 85. (Assume the data set has a bell-shaped distribution.
The mean score of a competency test is 65, with a standard deviation of 10. Use the Empirical Rule to find the percentage of scores between 55 and 75. (Assume the data set has a bell-shaped distribution.)
The mean IQ score of adults is 100 , with a standard deviation of 15 . Use the Empirical Rule to find the percentage of adults with scores between 85 and 115 . (Assume the data set has a bell-shaped distribution
SAT verbal scores are normally distributed with a mean of 489 and a standard deviation of 93. Use the empirical rule (also called 68-95-99.7 rule) to determine what percentage of the scores lie. a) between 210 and 675. b). Above 675?
If a variable has a distribution that is bell-shaped with mean 28 and standard deviation 7, then according to the Empirical Rule, 68.0% of the data will lie between which values?
The mean score of a competency test is 72, with a standard deviation of 4. Between what two values do about 68% of the values lie? (Assume the data set has a bell-shaped distribution.) a Between 64 and 80 b Between 56 and 88 c Between 68 and 76 d Between 60 and 84
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 __.
Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 65miles per hour, with a standard deviation of 3 miles per hour. Estimate the percent of vehicles whose speeds are between 56 miles per hour and 74 miles per hour. (Assume the data set has a bell-shaped distribution.)
Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 7171 miles per hour, with a standard deviation of 33 miles per hour. Estimate the percent of vehicles whose speeds are between 6868 miles per hour and 7474 miles per hour. (Assume the data set has a bell-shaped distribution.)
