In statistics, we use symbols to represent summary information. So, during the study of probability distributions, a format is used to indicate the random variable and its probability distribution, where each element has its meaning. Answer and Explanation: The given statement is: X∼b...
Given a mean of 60 and a standard deviation of 12, what is the area between 48 and 75 in the normal distribution? Use the 0.6826-0.9544-0.9972 rule. What is a typical deviation in statistics? Find the sample standard deviation for the following data set: 23 27 12 17 16 Find the stand...
An exponent of 2 is the mathematical symbol for squaring a quantity, i.e., multiplying that quantity by itself. Thus, x² means that x is being multiplied by itself. What does ² mean in math? An exponent of 2 is the symbol for squaring a quantity. To square a quantity is to mu...
Any symbol can be used, but the most common in statistics are i, j, and k. If x1, x2,…, x5 are the members of the x family of prostate volumes put in order from smallest to largest, we can say xi<xi+1, which is shorthand for the relationship that any member of the x ...
(this is also one of theAP Statistics formulas). However, if you’re finding the sample mean, you’re probably going to be finding other descriptive statistics, like thesample varianceor theinterquartile rangeso you may want to consider finding thesample mean in Excelor other technology. Why...
. For example, if the mean height of the sample of fifth graders was 50 inches and the sample variance was found to be 45, then the standard deviation would be 6.7. So most fifth graders would fall between 43.3 inches and 56.7 inches, which is 6.7 inches above and below the mean....
