We can easily calculate percentiles in R using the quantile function, which uses the following syntax: quantile (x, probs = seq (0, 1, 0.25)) where: x: a numeric vector whose percentiles we wish to find. probs: a numeric vector of probabilities in [0,1] that represent the percentiles we wish to find., In statistics, the 68-95-99.7 rule, also known as the empirical rule, is a shorthand used to remember the percentage of values that lie within an interval estimate in a normal distribution: 68%, 95%, and 99.7% of the values lie within one, two, and three standard deviations of the mean, respectively. In mathematical notation, these facts ..., SOLUTION: IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. If a certain person has an IQ of 131, what percentage of the population has an IQ lower than h Algebra -> Probability-and-statistics -> SOLUTION: IQ scores are normally distributed with a mean of 100 and a standard deviation of 15., We would like to show you a description here but the site won’t allow us., I was curious about my IQ to see if it was Mensa worthy, so I took the various online Mensa test (Norway, Denmark) and my score was 125-126 saying I was in the 95 percentile. I read somewhere that if you score 125 or higher it is recommended to go through with the real test to get accepted into Mensa. Is that accurate?
