1600-1500 = 100
So, that is 100/150 = 0.67 std above the mean.

Given a mean of 25 and a standard deviation of 2.3, what is the z-score of a data value of 29? I don't understand the formula they gave me for the z-score, so I dunno where to start. /:
A. In a given normal distribution, the sample mean is 75 and the sample standard deviation is 4. Find the corresponding standard score of the following values: 1. 69 2. 85 3. 70 4. 65 B. In a given normal distribution, the population standard deviation is
. A population has a mean of μ=35 and a standard deviation of σ=5. After 3 points are added to every score in the population, calculate the new values for the mean and standard deviation?
A population has a mean of � � 30 and a standard deviation of � � 5. a. If 5 points were added to every score in the population, what would be the new values for the mean and standard deviation? b. If every score in the population were multiplied by 3 what
set of data is normally distributed with a mean of 200 and standard deviation of 50. · What would be the standard score for a score of 300? · What percentage of scores is between 200 and 300? · What would be the percentile rank for a score of 300?
If the mean I.Q. is 100 and the standard deviation of I.Q. scores is 15, then an I.Q. of 130 will have a z score (or standard score) of?
The College Board reported the following mean scores for the three parts of the Scholastic Aptitude Test (SAT) (The World Almanac, 2009): Assume that the population standard deviation on each part of the test is = 100. a. What is the probability a sample
A college student takes a standardized test and scores a 163. If the mean is 155 and the standard deviation is 7, what is the student’s percentile rank? (Assume a normal distribution.)
A final exam in Math 160 has a mean of 73 with standard deviation 7.73. Assume that a random sample of 24 students is selected and the test score of the sample is computed. Assuming the scores are normally distributed, what percentage of sample means
