For what sample size would you expect a sample mean of 489 to be at the 33rd percentile? How do you interpret a standard deviation? Calculate the variance and standard deviation of the sample. What is the probability of getting a value of more than 1 standard deviation from th...
Given a normal distribution with a mean of 50 and a standard deviation of 4, 60% of the values are between what two values (symmetrically distributed around the mean)? For Normal Distribution with mean = 50 and Standard Deviation = 10 Find x...
Given a normal distribution with a mean of 25 and a standard deviation of 2.5, what is P(20 < X < 30)? Normal Distributions Normal distributions are a form of a probability distribution, where the distribution of values is symmetric and bell-shap...

By the 0.6826-0.9544-0.9972 rule in a normal distribution with a mean of 65 and a standard deviation of 5, find the 95th percentile and the score k that has 80% of the scores below k and 20% of the scores above k. If 15 students had a mean score ...
Find the z-score of the data value 98 for a population having a mean of 80 and a standard deviation of 8. (Round answer to 2 decimal places.) Suppose you have a score that puts you in the 60th percentile. What is your z score? How is that computed? Find the following...
In such a situation, a deep dive analysis should be performed to discover the reason for bimodality and, in the case of bimodal distributions, summary statistics such as median and mean can be deceptive and measures such as kurtosis and standard deviation will be extremely large in comparison ...
